I have a turbo 06 ctsv. It's manual and I'm trying to get it to 2 step more aggressively. Its really lazy on the lnc2000 to build boost. Ie takes 5 or 6+ seconds to hit 3lb.
I did retard by 13deg on the lnc2000 but not much luck. Still slow on the 2 step. This is a ls2 on 7875 turbo so it should light up like crazy.
I'm guessing it needs futher timing retard. Im usually launching at 4k. dont want to hack the main high octane table. Any other tricks? I'll attach an old tune. I've upped the ignition quite a bit since.
