the chip added a load of horsepower to my 2002 nissan xterra 3.3. i got a few better miles per gallon with the chip too. i’d buy again if i ever get a new car!

No support...product's instructions refer buyer to local automotive technician for help and/or instruct buyer to reach back to this company's support... that does not exist.

More importantly, the address shown on the products site is a beautiful home...whereas the buyer's payments are delivered to a lower class wooded house with no valid address...NOT credible!

I am still waiting for some one to help me return the chip unit I bought as it does NOT fit my car nor are there any schematics provided to help. I did get one reply from "bill" but his directions were not technically correct nor did he offer further help. Fact is, he is MIA after many attempts to get help.

If provided, I would lower my rate to minus zero..

Have send 4 or 5 emails to get a dang diagram so I can install this on my 2005 Ford Escape. I have waited 12 days and still have not got a diagram when it says 24 hour response time. Very irritated and disappointed with the customer service.

Very helpful and informative. Definately notice the difference in the car.

Excellent buy, after 30 miles started seeing improvement on mpg...was always running about 19mpg... now at 23mpg after driving 150 miles and still going up... but i have a led foot lol...u guys kept ur word...took 5 min to install and honestly I feel more torque and a quicker response when I hit the gas and by the way my 2007 Chevy Monte Carlo LT would stop the speedometer at 112.... now I'm getting to 120 was a little scared to go more cuz of police....too many speeding tickets...definitely recomend...thanks guys

Had one of your chips in my 2008 Tacoma, worked great, Hit a deer, got a new Tacoma, had to get me another chip, thanks!

Good product but you advertised customer service and that you would help get woring diagrams when i called i got 0 just told me they would call back. And when i emailed them i got 0 response.

didn't get to use the chip since i no longer have the vehicle but it seemed like a good product

FALSE ADVERTISING!!! No help with INSTALLATION! BOGUS Phone Number!!! Stay AWAY from COMPANY!!! Check the BBB!!!!!

The chip didn’t have install directions and there wasn’t a phone number where we could talk to someone. The number we had had no message available.
No mechanic could figure out how to adjust it.
It just doesn’t work.

Very Vague installation instructions. Very poor interaction with the so called experts, and even non response.

Product doesn't work and I want a refund

It seems to respond a little better than it did. The idle seems to be increased. I need to drive it for a while to be able to tell for sure.

Thanks
