Hi! I just installed the preditor performance tune in my 2005 dodge 5.9 and now when i'm in park and rev the engine to 1500-2000rpm the engine keeps reving for approx 10 seconds. I tried to do cyl test but was unable to with my preditor, is this something with the tune or do I have a injector issue?

This is not uncommon on a tuned cummins, best bet is to not rev it with no load
