Powertune Performance Chip

This is a Powertune Performance Chip review. This Performance Chip can be found on ebay from seller ‘powertuneperformance’.


Company Profile

The manufacturer is a company called Powertune Performance, from their product packaging. The website is powertuneperformance.com. One red flag about the site is that it is very basic and was created last year (2017). It has been our experience that these copycat NitroObd scams usually are new and pop up quite quickly. The proof will tell if this is a real chip or not.



The cost on ebay at the time of this review was $79.95, and the same cost was shown on their website. Again, this price range is VERY suspect, as no real tuners can be designed this cheaply. 


Product Appearance

Powertune Performance Chip Module


We purchased one of these modules from ebay for testing.

Immediately we noticed the first red flag – the size and shape of the case. There are at least five other colors and ‘brands’ of the same shape and size, but so far they all have been proven to be nothing but Nitro OBD scam clones. Hopefully this one will be different. Many products make big claims, but do they really work?


Internal Analysis

After removing the cover of the module, we once again noticed an old familiar circuit board design:

Powertune Circuit Board


If you were with us for the NitroOBD Performance Chip Scam, you will notice this identical circuit board immediately. The circuit board is built around a hidden SMD IC on the rear of the circuit board, which is a STM8S003F3 IC. Right away we see a problem here, because if one pulls up the datasheet for the STM8S003F3 IC, we see from the manufacturer, ST, that this chip has a maximum program memory size of only 8KB:

STM8S003F3 Datasheet


Online searching shows that ECU maps for a vehicle will be at least 20KB in size or larger PER MAP! This is way too large for the STM8S003F3 IC to contain. So, if this is the case, there are no genuine vehicle maps onboard this module. What can be stored in such a small 8KB sized space then? It would be perfect for a fancy light blinker – hmmm….

We looked a little closer and removed the circuit board from the OBD connector shell itself. What we noticed is another BIG fed flag:

Powertune Performance Chip Circuit Board Back

There are only a total of eight connections to the OBD shell. All other pins are NOT CONNECTED! Here is a view of the actual OBD shell:

Powertune Performance Chip Circuit Board OBD Connector

Notice all pins have been cut short so they will not touch the circuit board except for the following pins: 1, 2, 3, 4, 5, 14, 15, 16. What does this mean? When we check the OBD protocols and which pins they require, we will see another red flag:




From this chart, we see the following protocols and which pins must be present for them to be used:

CAN – 4, 6, 14, 16, PWM -2, 4, 5, 10, 16, VPW – 2, 4, 5, 16, ISO – 4, 5, 7, 16

So we can conclude from this that the Powertune module:




The only protocol left, VPW, is used on a very small number of vehicles. The vast majority use CAN or ISO protocol. This is the final nail in the coffin – even if the chip were somehow able to produce some magic, the pins needed for most vehicles they claim it works with are not even connected to the circuit board! However, the two most important pins, 4 and 16, which supply GND and +12V to power the light blinker ARE there 😉

In addition, the module claims to be custom programmed for a specific vehicle model. If this is the case, where is the programming port to flash the module with the vehicle programming? There are programming connections to the left of the stm chip, but they are inaccessible once the circuit board is assembled. Why is this significant? Because it proves once again, like the NitroOBD scam, that the chip is programmed with the light blinker program BEFORE it is assembled! This means the same program is used in all modules and it is impossible for it to be custom programmed for a specific vehicle.



We connected the chip to our 2012 BMW 530i 3.0L L6 as instructed and the lights came on as expected. The lights began to blink in the same sequence as the NitroOBD chip did.

We followed the instructions and drove at least 200+ miles to give it the benefit of the doubt, and…… nothing. No power increase from the Powertune Performance Module, no fuel economy gains – nada. We did, however, see a neat light show in a pretty white colored box!



It is clear from our analysis so far that the Powertune Performance module is nothing but another Nitro OBD light blinker scam. From others on the web, there are reports of ECU damage from NitroOBD, and, being that this is most likely the same thing in another colored cover, there is the possibility of vehicle damage at worst, a pretty light show at best.

Another interesting area to research is the Userid histories of these scam sellers on ebay. Most of the time, legitimate performance companies will only change their ebay seller name only once, or even keep the same name they had when they first started selling on ebay. Not always, but most of the time, these scammers will change the name of their seller account Userids several times, trying to look ‘official’ to buyers and better match the garbage products they are selling. Our lookup on powertuneperformance’s past Ebay Userid history shows this is indeed the case with Powertune performance chips:

This shows us that only recently, approx one year from the time of this review, this ebay seller changed his username to match his product – around the same time he began selling these scam chips. This seller has tried to sell everything in the past from nutrition products to antiques to manuals, and it now looks like he has finally found a good market for suckers. This is even more evidence to fuel our suspicion that this is just another scam.

Also, it appears some buyers on ebay are beginning to figure out this scam and know it can damage vehicles due to the low quality:

Our message to the company:


We are an automotive performance chip review group and saw your performance chip. We have a few questions about your product:

1) Can you assure us this is not a NitroOBD scam? If so, why does the PCB inside look EXACTLY like the Nitro OBD chip?
2) Do you have any real-world proof of your performance?

Thanks for helping us to gather more information about your product for buyers on the net!


Company’s response:


They did not even attempt to defend their junk product.



From our research and review, it is our opinion that the Powertune Performance Chip Module DOES NOT WORK. You will DEFINITELY want to avoid this!

  1. My mechanic said your chip does not increase horsepower overall. He said it tricks the computer at high RPMs that engine is cold which increases fuel flow. I want 10 or 15 more horsepower for my Corolla S. Please respond, I want facts not just a opinion. Thank you

    1. Thanks for your comment. We do not make the Powertune performance chip – it is a scam. Your mechanic is correct, but it is even worse than that. It does not even do that much – it only blinks lights. It is a SCAM.

  2. Corolla S, need about 15 more horse.
    Does your $79 chip truly give that. Please email me a responce

  3. WOW Im glad I found this site, I just my PowerTune chip in the mail. before it cam Iwas like let me dig deeper on this thing before I go plugging it into my 2009 Ran RT lol, thank you for the Imfo to find out it doesnt do any of what they say & might damage my trucks computer? HELL NO!!!!! I got my on Amazon lol its going asap.thank you again Guys keep up the Awsome work!

  4. Thank you for the awesome review I found one of these chips in a trade in car and was gonna give it to my little brother so he could feel better about his car. So I just tell him to save up and buy a real modification for his car like a better exhaust system.

  5. I bought it 2 months ago for my BMW 428i and I felt absolutely no difference with it. Waste of my money. What should I do with it now?

    1. Sorry you fell for this scam. Check with your payment company, whether PayPal or credit card. You may be able to stop payment because it is not as described. You could try asking the seller for a return but these scammers rarely reply when asked. Good luck

  6. Just received my PowerTune Performance Chip in the mail from Amazon. Luckily I found your reviews on it and other performance chips before plugging it in to the OBD port on my car. My only regret is that I did not find your website sooner! That scam chip is already on its way back to PowerTune. Thank you!

  7. You tell the truth – I found out too late this is a fake chip. I purchased from amazon and used it on my 2013 civic, now I have abs error light on with no improvement whatsoever. Will be shipping it back asap. Others be warned!!

  8. Seems to have helped add about 1 mpg with my 2008 escape, although it may be driving different styles and locations – not sure. There definitely is no power increase so far that i can tell

  9. I emailed the seller and asked, “how do I remove it”, and he quickly replied, “simply pull it out..”

    Then, I emailed him: “How come one of the reviews says this is a complete scam, similar to the nitroOBD scam. it also goes to say this chip only has 8kb memory.. not enough”….. and its been over 30 minutes, no response! Wow

  10. Stay away from these chips folks. Think about it for 90$ if it was supposed to add so much this and so much that,how come it’s just not factory installed? Or even better,why are they so cheap? That alone should give enough red flags to stay far far away from a “Plug in magic box”. There is no magic pill for life,same goes for cars. You get what you pay for. Either buy a better car you can actually tune (Not a 2002 Buick Lucerne) 😂. Just put a intake maybe or exhaust but again buy a car more available to tune then grocery getters. And I’m not knocking anybody,I got a 2004 Buick Lesabre 😂 So what I speak is the truth. I was looking for some performance like others and glad I looked into. Stay away,or get an actual flash ECU from a reputable tuner shop,get more “tuner friendly” car. Those are you realistic options. Great review however. It does inform those who don’t wanna listen and wonder why they wasted 100$ or more.

  11. I just installed this on my 01 Ranger yesterday and it wont stop blinking red so I looked up solutions and came to this, wish I saw this sooner. Anyways, how easy do you think it will be to get my money back from this scammer?

    1. This depends on how much time has passed since the purchase. Occasionally you can request a return / refund if it has not been too long. Otherwise you will need to open a case with your payment company, Good luck

  12. Just want to say Thank You for your review.

    Their product popped up on Amazon, as a suggestion for my car, twice with different part numbers but the same generic description. Neither one appears on their website, just one entry for the vehicle manufacture.

    I’m not sure I would have purchased their product just because they gave no useful information in the description. But your review differently gives the information I need to NOT make a purchase.

    Keep up with the great work and thanks again.

  13. I always do my research before buying something that makes impressive claims at a very low price. Thanks for your research and review. This “chip” is offered on Amazon. People should do their own research so they can make an informed decision before purchasing this item.
