Truthfully the money you spend wont cover the Seat of the pants improvement you get. Its hard to see any real performance from N/A Audis. I had a new V10+ and had it tuned for $3000. Felt more like $300 worth. I am now looking to purchase a salvaged new body style R8 and and Salvaged RS7. Then I will put the twin turbo V8 into the R8 and chip it up to 750hp. It will be all factory appearing and factory wiring
