Would a tune make much difference on my car?

Get a higher stall torque converter- best mod for an A4.
Get a tune- some cars run rich after installing LT's, and the LS1 tune from the factory is very conservative- leaving power on the table.
Higher temps and humidity of summer should make your car slower (assuming your baseline times were in cooler conditions)...if you are running the same times as you ran in better air, you have picked up some power.

with my cat back set up I went 13.1 at 107.8 then went to my true dual set up and went 12.84 at 111.8 and then tuned it and it went 12.76 at 111.2 I ran 5 psi lower on the the tuned run and didnt air up the front either. thats why the MPH was slightly lower.
