What kinda of power gains should I expect from a bolt on tune
 

01 trans am, ported tb and maf, slp air lid with k&n drop in, pacesetter longtubes, catless slp powerflo are all the intake and exhaust goodies I have at this point. The guy I am planning on taking it too just did a Camaro, I believe he said 2000, with similar bolt ons and he picked up about 35 hp at the wheels to 335 he said.

Are these decent numbers for the mods listed? I assume I'll make a little more cause of the ls6 intake.. Just wanna make sure I get good power after dropping the 600 on it and want to see what you guys think it should be making with those mods from your experience.

I have a predator diablosport tuner now but it's running lean as hell according to the 02 sensors, and they are covered in carbon build up, so I can't pass emissions so that's my whole main reason to get it done

It depends on the dyno of course, but 330-340 rwhp for the auto and 340-350 rwhp seems about the norm from what I've seen

I would think you will pick up 35-40 rwhp. Are you a m6 or a4? Reason I ask is a lot can be gained in a transmission tune in the a4's also.

I'm a a4. When I was bone stock with 2.73's I ran 13.8.
Then put Lt's and tune only and ran 13.2 with those being the only changes

I'm m6 and they have a mustang dynojet 1100, which from what I've read is a pretty impressive piece of machinery
