First, good thread, LBGT.
That's good, but a professional tune does not equal a good tune. Often it does, but certainly not always. Safety, especially boost control for 4th/5th gears often gets compromised. Anyone paying for a pro tune needs to log it.. at least once... as outlined by LBGT above:
If a buddy comes over and says, "I got 10 mins, make sure my tune is safe", this is what I would do:
-IAM at 1.0............................Check
-learning view looks decent (prefferably all 0s in the high load column)..........................Check
-I would also make sure AFR learning (also in learning view) is within 3%....Check
-take it out and beat on it, WOT runs, lots of high rpm shifts, etc.......If I saw very little FBKC (maybe the odd little bit occasionally after a shift) I would tell him his tune looks reasonably solid
I would not have peace of mind with a protune and never having checked it.
