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

New life for an older truck

Reviewed By william s (WINSTED, CT) Reviewed for a 2004 Chevy Silverado —5/22/2016 5:38 AM

I bought a new rv last year, and was unhappy with the trucks pulling performance....so i did some research,and found a tuner would do the job....i did not need all the bells and whistles..just something to change the timing and shift points....this unit was just the ticket....and it was on sale.... cant beat that....have set it to tow mode and it made a big difference....i live in new england (lots of hills)..and no more overreving to pull them...my truck works within its power band .
