I have a 2004 sti running a tek3 remap to 340hp and a standard vf35 turbo/actuator running 1.4-1.5 bar but dropping boost to 1.1bar, I have recently uprated to actuator to a forge motorsport with uprated spring to keep the boost holding. this now only seems to peak at around 1.2 bar MAX, yet it has a much stronger spring than the 35??

any ideas guys??

Cheers

Paul
