Have a friend who has a 297kw r8 with a couple of mods from Brock Shop, exhaust and a couple of other minor things. I am wanting to see how my T will perform in comparison. Would like to have a bit of a clue of the difference between the 2 before we have a run. Mine is 04 Auto, K&N, 2nd Cai, and edit from CV arriving today (hopefully) Anyone had a run with one of these? Or have an opinion on the outcome?
