sunnydays said:Yeah, look at some of MHD ots maps for example. Stage 1+ puts you at 390bhp on the right octane fuel. Obviously watch your IATs. These OTS maps are relatively conservative aswell.
Head over to the e90 forum n54 section, plenty of people hitting 400whp with a tune, dps and intercooler. Upgraded charge pipe, fresh coils and sparks usually too
Good stuff! I'll be sure to take a look over there
Regarding tyres, I was planning on going for Pilot Sport 4's once the current P Zero's have worn out, I suspect the Pirelli's being run flat's is causing most of the issues there
Anyway, this is thread jacking, get a 35i OP
