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.

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.

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.....
