So I'm about to go from DHP on the 3800's to dealing with GM's SCT dealer software and wondered if anyone has actually used the SCT GM stuff. I'm looking for tips. I know to tune for SD first then enable the maf and work that back. I'm looking for some insight if you've used it an have any advise! Thanks in advance!

I'm dealing with an LQ4 with LS3 cylinder heads and intake with a 90mm Edelbrock TB and 4L80e in a 70 chevelle if that helps at all. Right now I've found the LS3 injector tables so I'll be starting there and working the VE and Maf tables to hopefully end up running where I want to. I'm a complete newbie to SCT on a GM so I would really appreciate any help if it's available at all
