I am usually getting 15.3psi (in the upper gears) under full throttle using the accesport as a boost guage. It will sometimes hit 15.6-15.7psi, but not often. I have turned the wastegate a 1/2 turn and it helped, but is it normal for the vaccum pressure to decrease? Before the 1/2 turn at idle the wastgate pressure on the accesport guage was 10psi, now it is 8psi. What is everyones stage 2 boost using the accesport as a boost gauge? Does it make sense to give the wastegate one more turn?
I have tried resetting the ecu and I am running the newest stage 2 map. Mods: helix downpipe, gutted uppipe, spt catback, samco I/C hoses.
