"I got this chip for my 2001 mercury cougar v6. Installation was easy and only took about 15 minutes. My cougar has some performance upgratdes inscuding but not limited to short ram exhaust soon to be turbo, cat back performance exhaust and headers. I was looking for a stage 2 PCM because of my performance upgrades, but there wasn't one for the 01 cougar. So in spite of what I thought, I bought this module hoping that it would help increase some performance on the car. As it turns out it did, and I can see a slight increase in hp and tourque. Great Product for the cash." —Josh L from Aurora, CO bought a Jet Performance Module for a 2001 Mercury Cougar, Automatic, 2.5L V6.
