Current situation, 392 stroker running custom diably tune from hemifever. Superchips seems to be the only tuner than can raise the rev limit on 03's and apparantly it's possible to stack the superchips and diablo. Has anybody actually done it and how is it done does it matter in wich order you use the tuners and info like that? On a sidenote, anyone has a superchips tuner they wanna get rid of? Let me know.
