2008 Ford Crown Victoria P71 Police… 2008 Ford Crown Victoria P71 Police Interceptor 4.6l. Factory dual exhaust which I removed factory muffler and installed 2 FlowMaster single chamber mufflers along with a K&N filter in factory box( since that truely pulls cold air from outside engine compartment). These vehicles come from Ford with high performance tweaks already. I installed the Stage 1 Performance Chip and within about 150 miles I noticed much crisper throttle response and firmer shifting! Along with an Awesome WOT!! Ive tried other performance chips and IAT splice in chips but nothing compares to this simple plug and play chip, best $100 you can spend to "wake up" this 4.6l ! I just upgraded to the Stage 2 Chip and will post a review after a few miles. I am a gear head and have been wrenching for 40 yrs. Living in California I just wanted this car to get out of its own way and Performance Chip answers that problem. I do own and build hot rods/muscle cars. This P71 is a shop car/parts runner.

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.

Can't get ahold of them to return a… Can't get ahold of them to return a product Update: Got a call from their customer service department. 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!

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.

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.
