I'm pretty sure my last RS4 wasn't producing anywhere near the quoted figures, never had it tested as I'm not into modifying cars really. I've been thinking about this and am willing to spend a little dosh to free up the engine somewhat. See below - other options or suggestions would be muchos appreciated.
Option 1 - Carbon clean on its own should it need after a dyno run - £975
Option 2 - Carbon clean with Stage 2 manifold and map £2200
Plus - Miltek non res valved £1960 (Just for the sound as standard exhaust is a little quiet after a Porsche sports exhaust!)
Option 2 and the exhaust are going to cost me a considerable amount, are there any other options open to me?
Cheers
Dave
, both MRC and Unit 20 said they would do this for me.
