Does not work as Advertise at all! I got the chip stage 2 for my RAV4 and I let it in the car for 3 weeks (instead of the 2 suggested) and not only didn't improve the miles or give me more power but on the contrary I felt the SUV to be more lethargic then usual, and the miles when down by 3! I paid for shipping back ($11.15) and they also charge me 15% restocking fee?!?@ Their website states 100% money back warranty. I will not recommend this company to my worst enemy!! Update: They reply with lies as you can see below. I have contact them and send it back in the original box with no a scratch in the time allow. I have all corresponding messages and pictures.

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!

Stage 4 power chip Amazing product, easy to install, looks great on dashboard. Great company they are concerned about their clients.

Great Product, Great Service I bought a stage 2 chip, and though it was a significant power increase, it caused some surprise redline downshifts with my transmission when letting off the gas after full throttle. Contacted customer service who were very helpful. Replaced it with their JDM stage 3 chip and it is performing flawlessly. My Crown Victoria is now positively FEISTY!!!
