Finally got some times on my SS.

2005 Silverado SS AWD. Mods are AEM CAI, Crapmaster D I/O drop in, HD-2 shift kit with Vette servo and a Madtune.

Before the tune
14.54

After the tune
14.30


The tune was very mild only adjusting PE, shift points and the rev limiter. After we left the track I tuned everything and gained another 1.5 or 2 tenths at least but we'll get those numbers soon to verify.
