My buddy has Gto that was previously tuned. It smells real rich at idle and doesnt seem to pull as well as it should for being a cammed LS2.
His mods are CAI, LT headers, and Custom Cam with specs
235/243 .620/.623 112+1 LSA
Here is the current tune. I myself am new to tuning and have yet to go to any of the live seminars to learn anything so I can't help him any yet.
Let me know what y'all think.
