Hey Guy's

Hated to put up a new post but could not find anything on it. I have 2001 L with quite a few mods, however the tranny is stock and stock converter, but the L is shifting 1-2 around 5700-5800 2-3 around 5200-5400- and 3-4 don't know. I feel this is to high, how do I set the shift RPM lower. I have headers,cat back exhaust, JLP Ram Air intake, Steig Ported Blower and Steig Dyno Tune w/ sct flash programmer (old style), Methanol Injection, 6lb lower, TR-6 plugs, TB, C&L Truflow tube, & 58" T-Bars . I am assuming that I need to have Steig change the shift points in the tune, is this correct?

YOur SCT tune controls the shift points now. Go to your tunner, or SCT's web sight, and down load a Costum Tune.

 

Thats what I thought, just wanted to make sure before calling them. One other thing; do they need the vehicle to tune the shift point or can it be done w/o the vehicle and just flash it later?

 

You have'nt by chance changed tire diameters? I went to a taller tire last winter and had the same problem. Chip was tweaked and now it's fine. Just FYI.
