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

Huge increase in performance. No turbo lag and the diesel runs smooth. The different settings allow for programs for towing, fuel economy and performance. The performance setting has increased fuel economy.... As long as I keep my foot from stomping the gas pedal. Increase from 11 mph around town to 14 mph. Not tested on the interstate yet.
