250BHP??!!

IMO, a Stage 2 T3 is on its knee's at 225bhp and it will only go that far with a very good map.

D4nny8oy on here has approximately the same spec as you, but with a Newman solid lifter cam and VEMS management and that makes 225bhp, but I mean a proper 225bhp (measured on an accurate Dyno). From memory, its around 190bhp at the wheels. It's running moderate boost and I strongly believe it's limiting factor is the exhaust housing.
