I took my maroon Z out last night to see what she could do.I raced a Mustang with some work done to it and of course I beat him but with a little bit of a problem.
I set my new Greddy Profec Type S(updated profec B) boost controller to 14 psi but when I raced him I would only boost up to 9 psi quickly then after a second or 2 it would shoot up to 14 psi and then I would pull on the Mustang.Same thing happened the rest of the night.
I have a 60-1 with an O trim exhaust in a ported stock turbine housing with a stock internal wastegate.
Could the problem be the boost controller or the old stock internal wastegate actuator? Do you think by adding a spring to the wastegate flapper like Jason's might help or maybe adjusting the gain on the Profec? I changed the gain setting last night but it didn't seem to help.
The guy in the Mustang said it looked like I shot a little Nitrous when the boost would shoot up from 9psi to 14 psi.
