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.....

Tundra +JDM stage 3 performance chip I purchased the JDM stage 3 performance chip for my 2018 tundra Crewmax After only 2 days i was noticing faster and smoother shifts with a slightly quicker acceleration. I can't wait to tow my boat and see how it acts. The chip is easy to install and works well along my k&n intake and flowmaster exhaust.

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

Chips don't work and could cause electrical issues I personally used this chip for 6 months now and have driven close to 5000 miles with it. They do not do anything at all to your vehicle and could cause electrical issues like what happened to my 2010 Ford F-150. I did some more research and it looks like they have two reviews blogs that they own, one to help give positive reviews to their chips and one to give bad reviews to competing chips. I am not saying that you shouldn't buy from them, I am just saying that you should do a little more research before you spend your hard earned money on something that could harm you car. Tried to contact them 2 weeks in and they kept giving me the run around then they said they couldn't help me or give me a refund, its a shame, I really wanted to like this company and their chips.

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!
