Little to no gain

Reviewed By Patrick S (Methuen, MA) Reviewed for a 2001 Mercury Mountaineer —4/10/2007 4:37 AM

I have had the Jet PCM installed for a little over a week and noticed little to no gain in performance installation was easy but clean the s%#t out of the stock connections or it wont work. the only gain i noticed with the chip was when i changed the spark plugs to Bosch Platinum Ir Fusion. Modes done to suv 5.0 with cam/supercharger intake with 95mm mass airflow and magnaflow true dual side pipes best 1/4 13.9

Easy To Use Performance Programmer

Reviewed By Larry F (Millington, TN) Reviewed for a 2003 Chevy S10 Pickup —9/18/2017 1:31 PM

This programmer could not be any easier to use. I recommend going online and print a copy of the instruction manual (about 5 or 5 pages) because there were no instructions with the programmer. Most people won't need the manual, but nice to have. I went for the highest setting that requires high test gas, firm shift, and 10 mph higher shift points. I did notice a little more power, but the real winner was the transmission, with much better performance. Good buy!
