Improved milage but when I had to go back to stock the milage stayed the same . Point is I am not sure if it did anthing . The one thing I will say is it keeps trans in gear loanger before shifting . Overall 3 stars .

Little to no gain

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

Does what it says

Reviewed By Taylor M (MESA, AZ) Reviewed for a 2014 GMC Sierra —1/26/2015 9:06 PM

2014 GMC Sierra 1500. Fairly easy installation. Manual days you need to remove several fuses, but this is not necessary. Just make sure headlights are off, radio is off, and nothing is plugged into DC outlets. Did what it said!
