googz, one more thing i could recommend is possibly hi-flowing the turbo...I've got a T03/T04 hybrid turbo which has been hi-flowed by the previous owner , n I've made 270bhp at 15psi after installing an S-AFC...with no fmic. Once i get one on, my tuner expects 300+ bhp, and for me to do a 12.5 run at willowbank...the bastard!
anyway, the S-AFC gave me 66 more hp, so i would say get that first, then an fmic, then see what u can do to hi-flow ur turbo...if u're looking for crazy horsepower and a clean torque curve of course.
