On the road im seeing a 32psi peak tailing off to 27psi, I dont know what boost it made on the rollers but think it was a DD set up will pop along to Sitech during the week to pick up the printout.
Its the smaller GT3071 so its about the power i was expecting around 450, but its the way it drives im more than happy about. For a 380bhp + road car its the best turbo ive used, Ive had T34.55, T34.63,T38 and a roller T4.
