Looking for the best tuner that can give my truck more HP/TQ, throttle response, transmission and engine “sport” tune

The 8 speed transmission can not be tuned in that truck... Can't do anything about the tranny shifting... only the ECM/engine can be tuned....

You'd want the inTune i3 8246 Platinum or the Trinity T2 EX 9246 Platinum...

the tcm would need to be removed from the truck and shipped out somewhere to be unlocked.
