Hey man ! You are very welcome. Have the answer for this too. LOL Mine did this a few times also. Its the HOT start and idle set on the tune. My First issue was mine wouldnt start after it was warm, Too much fuel( hot and cold starts where set the same?)
I had one step colder plugs too, along with bigger injectors, My tuner ironed that out if 20 mins
An to be really honest. I LOVED my Stillen kit, Wish I could have kept is, The 457WHP is made was MORE Than enough for me.
