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.

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!

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.

It cost me a $200.00 repair bill It cost me a $200.00 repair bill for my 2007 Cadillac Escalade. The performance chip interfered with my EBS and Stabilitrak system. It affected my ride, and my braking, and after taking it off and throwing it away I feel like I'm riding in a completely different car. Whatever difference it was to supposed have failed to materialize after 1,500 miles.

It actually does work.... OK... finally got the miles on the chip that they required. It actually does work. Not sure how much horse power it added to the car but I can tell a difference in acceleration and shift points. I did hear back from the company about the questions I ask.. about a week later. I guess later is better than never... I am gonna get one for my 6.4 Ram next.....
