Hey guys.
I'll start with my problem.
I lose boost (i mean 0 psi, zip, nada) at 6500rpm ish most of the time. I say most of the time as once in a while it won't do it and be fine to limiter. Other times it will only lose a few psi and then kick back to 14.
So 95% Boost Drops to zero and my car loses power.
S1r33 gtst.
Mods.
Hyper gear high flow.
Project b 2 set to 14psi.
Yellow jacket coils.
Fmic.
3in tbe.
Walbro in tank.
Nistune.
Factory intake modded so it doesn't suck closed.
Tune has been looked at by 2 well known tuners and they both think its not the tune. But something else.
Now when I run the car at 10psi it doesn't seem to have the problem.
this leads me to think its in boost control.
So is there anything I should be looking at with the profec b?
Could the actuator be adjusted in any way?
Thanks peeps.
