Does what it claims Does what it claims. Put Stage 1 on my 2007 Accord V6. Immediately noticed car running smoother, more responsive gas pedal...seems to react higher on the pedal too. After 48 hours, it's still improving. Transmission shifting more softly, can feel a smoother power band. Found two reviews by professionals online. Both came up with similar results. Worth the money.

I don't know why they didn't receive my email, but they really stepped up to the plate to resolve my unhappiness. They were really great to handle this situation after contacting me. PSA: The stage one tuning chip is the bomb!

They change their website page to try… They change their website page to try and hide their identity because so many people were having problems. Look at some of the comments the way they talk about their customers they call one guy troll. He’s not the one selling products performance chip tuning is a rip off and the people that work here are just as bad, they don’t mind stealing your money

GTE Stage 1 Chip 2018 Maxima Like many people, I was a bit skeptical about buying a so called “performance chip” to plug into my OBD2, as the online forums for my car state that even the best tuners out there haven’t been able to crack the ECU or do much to enhance the performance for it. But I decided to give it a chance, and for $99 and 60-day guarantee what did I have to lose? It came in 3 days just as the sales rep told me, and after about 15 mins of installation I noticed a major difference in the power and torque/throttle response, no placebo effect here. I drive my car regularly all day most days and am very accustomed to it’s characteristics, and though the 8th gen Maxima is already a quick car, this chip added that missing “fun-factor” I was looking for! Couldn’t be more pleased with this product especially for the money. I’d imagine it could take $1-2k to get the same effect other ways. Only other mod is K&N drop in filter which I already had for a while and run 93 octane. Now I’m just curious about the Stage 3!

It actually does work.... OK... finally got the miles on the chip that they required. It actually does work. Not sure how much horse power it added to the car but I can tell a difference in acceleration and shift points. I did hear back from the company about the questions I ask.. about a week later. I guess later is better than never... I am gonna get one for my 6.4 Ram next.....
