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.

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.

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.

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!!!

So people if you get one through three stages you want be disappointed ! Well people like they advertise that it is no gimmick, well it's not I got a stage two for my 2014 Silverado and another of the same for my son , he has a beautiful 2011 black SS Camaro that still has under 50.000 miles on it and you can tell the acceleration in both his and mine such a big difference! That is what I like about the chips there is no hesitation anymore and when you are rolling down highway o yea and hit it around other slower traffic big difference. Now as far as gas mileage well I think it is about the same that I was already getting ,but I am very happy with them . I have got two other friends to get them and counting . Alright Smarttune performance chip manufacturer all that I put in this review is true and very happy. I should get a stage three for all the sales I have sent your way lol .
