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
