I have alternative autos 87 and 89 tune. Does anybody know how much timing was changed from stock. Is it advanced or retarded any? I am thinking of putting nitrous on but I want to be at the stock timing.

 

Timing has been advanced on both of you tunes. I talked to lidio and he set me up with a nitrous tune....it has all the good stuff but has timing retarded for the 100 shot. If you want to spray 75 then do it with your stock tune not the alternative ones. Good Luck

 

How much did the tune cost? Also can he email the tune or does he have to load it on there?
