I can tell you that with no names spelled out that if you do get a tune from a tuner here on C5 depending on who you go with the only change there may be is with the rear O2 turned off.

I have HP tuners and compared the file to my stock and that was all that was done on a manual (mine)

Auto's can benefit more with the trans tune and a real tuner would also dial in the engine as well. I'm just saying don't expect a e-mail tune to optimize the air/fuel as most do not have a way to check so they pay these guys lots of $$ for not much in the end. It's gravy $$ for these guys at the level you are looking at.

And forget about trying to go aggressive. That did not work out well and had to go to a real tuner to get my cam tune set up properly. Spent too much $$ and time otherwise.

My suggestion is if you are not comfortable yourself a local shop might be a better way to start off instead of going to them anyway.

Best of luck in your upgrades and enjoy.. You won't regret the LT's & CAI!!
