uprated exhaust sytem...
I.e. Free flowing - Performance Particulate filter etc VERY expensive I would think, but probably the biggest gains to be had.
Matched with a good open filament air intake I would imagine you could see at least 20 30 hp.
I doubt the intercooler would have THAT much of an effect, has it been tested ? Seems to me the stock jobbie is pretty good, given the low volumes of air the turbos are actually pushing and the relative CRAP-NESS of our cold air.
Even on the petrol model the intercooler is a bit of a doubtful mod, Eugen seems to have had good results... Let's see what Tony's does. Tone you gonne get dynos before the intercooler with the re-map so we can really get a good benchmark ? Remember you'll need to let the car adapt to the new map too, so we're talking at least 50 70 miles between remap, dyno etc
