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. PSA: The stage one tuning chip is the bomb!

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.
