2006 Dodge Ram 4.7 I wread up on the JDM stage 3 a few months ago, an, actually put headers on my truck like days before the device arrived. I'm running 22x12 on 33's so acceleration/ power has always been a must! The thing bleeps every 10 seconds like a alarm system, but, my Dodge came alive within the hour of plugging it in. I love it, and won't drive far without it ever again.

Beware of Electrical Issues I am no expert but I did notice performance gain on my 08 Chevy HHR SS. The problem is the chip caused some electrical issues. When I first installed it some fuses were blown immediately. I replaced those thinking its just a one time issue. Used the chip for a few more weeks and then one day the ABS light came on. Took it to my mechanic and it turns out that the ABS module/system was gone. Now I cannot say its due to the JDM chip but I had never had electrical issues with the car before installing the JDM chip. So yes it does increase performance but beware of electrical issues at least if you own the HHR SS. No plans to use it anymore. Will go back to my Pedal Commander which has always worked well for me. Yes I know they are not the same but I am not trying to race anyone.

Does what it says I purchased a stage 2 chip for my 97 pickup and noticed a difference right away. Power, throttle response. Haven't seen a huge change in gas mileage yet probably because I have been enjoying the new feel of the truck a bit much.

Let’s just say I got dyno sheets to… Let’s just say I got dyno sheets to prove these chips are garbage. I have 1/8 mile and 1/4 mile times that say they don’t make any changes to ur car. Tried out on two different types of cars save ur money. I am thinking about starting a class action law suit so people stop getting scammed. If interested let me know you can call my attorney.

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.
