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.

Great Product, Great Service I bought a stage 2 chip, and though it was a significant power increase, it caused some surprise redline downshifts with my transmission when letting off the gas after full throttle. Contacted customer service who were very helpful. Replaced it with their JDM stage 3 chip and it is performing flawlessly. My Crown Victoria is now positively FEISTY!!!

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.

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.

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.
