Canned tunes are not the best. John Kennedy has some very refined tuning that is safe and will give you more benefits than those basic plug-in tuners. I also highly recommend one of Kennedy lift pump.

Anyone have problems with these trucks when they are tuned and still have the EGR valve and stock exhaust
No problems at all when you go with a reputable tuner.
