Again. Not for the faint of heart. No one knows. We can assume the N55 Steptronic is just as capable as it was with the N54 (which is pretty good aside a couple hiccups in some isolated cases that are being addressed). Personally I'm more concerned about the actual N55 engine. We have no guarantees on any front about the rest of the car holding together, we simply are supplying the kit that will actually have the potential to provide the airflow necessary to make some real power. This rest is up to some pioneers ready to take on a challenge and put their bets on the N55 being a real performer.

Also, those interested in a kit like this likely would not be interested in also running the stock intercooler (although possible) as it is just not a good idea. When performance is your game, you really should do it all right IMO and this means not leaving very insufficient components in the system. In short, buy an Intercooler.

Thanks,
Rob

If someone where looking to stay as stock as possible, like just a JB4 w/ E85 and upgraded turbo, how much gain can be expected(and will a FMIC be needed at this power)?
