Turbo engines like the 2.7 biturbo will always yeild far greater gains from remapping compared to naturally aspirated engines such as the S4s V8.

Which company quoted those gains?

The company that quoted those gains where angeltuning.co.uk - not sure if you have heard about these guys ? what kind of gains im i expecting to get exactly and would you recommend revo tuners ?

And whats the chances of fitting turbo's into the N/A versions ?

I know im not gonna get bike performance out this thing ( like my turbo busa ) but i am looking to get it over the 400bhp mark

I do have money to play with..

Virtually nil chance. You can fit a supercharger (MTM) but at a cost of c£10k. Yes £10k !!! Adds about 100bhp. QST have a B6 cabrio with one fitted.

Wont get it over 400bhp. Max is c380bhp. That's with a full exhaust including DPs, air filter, custom map, manifolds and possibly even race cams... Quite alot of dosh for the gains. It's a NA engine, so limited. That said, with 380ish bhp it'll be as quick as a B7 RS4 (so long as you upgrade the suspension)...

Hmmmmm . . . jack of all trades, masters of none (just like SuperShits). I'd personally avoid.

EDIT: their website is illegal too - completely fails to comply with many aspects of UK consumer legislation. :roll:

Either go with one of the major VAG only dedicated tuners such as Revo, or try MRC.

Prety much what stumpy has written although the manifolds and cams are not a must have to achieve noticeable increases over stock. See here http://www.rs246.com/index.php?name=PNp ... 114#367114. The cost for all my mods is about £1500.

As stated in the post with a better start the 1/4 mile time will drop further. Although the trap speeds are consistently strong. There is a car in the states that has easily gone below 13s. This car does have more mods than I care to state.
