didnt realize how bad my exhaust leak was while it was getting tuned and after fixing it the car drives a lot better (imagine that) but now my afr is pretty much a constant 14.0 to 14.3 and exhaust doesnt pop and crackle like it used to. is this something autotune can fix?

 

Set your target afr table and autotune until you're happy with the afr.

 

By "fix" do you mean to get the AFR's where they should be, or do you mean bring back pop and crackle?
