I have already done this and the power figures quoted are a little false. I've had a aem fic fitted and mapped and get 270bhp (220 at the wheels). This removes the afm. The clutch cannot handle the torque the 3sgte puts out and slips. I have a helix clutch fitted that is a bit of a hybrid (3sgte flywheel + cover plate, 6 paddle helix 3sge plate). I custom made my engine loom from aircraft grade wiring. The fuel pump is ok but if you up the boost even 1psi it'll blow the engine, so put in a gt4 pump. A 255 would make things too rich. A front mount intercooler is a must!!! I have spent two years ironing out all the bugs so be patient do things right first time!!!
