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.

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.

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

Great product and great company. Great product and great company to deal with. There are quite a few performance chips out there so a little research lead me PCT. it does as advertised. I ordered the Stage 1 for my 2016 CX-5 and after setting it up, the Mazda is purring like a kitten. It idles better, definitely is showing a performance enhancement and I can garner from these immediate results, the MPG is going to improve as well. Very happy with this addition to my SUV.

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!
