Need Help

[v8etr]

I have an 87 turbo t with alot of bolt ons (heads, cam, turbo, front mount etc...) and when it hits around 10lbs of boost it studders and won't go any further than that.
I have replaced th mass air meter and the coil pack & ignition mod.
Thanks

do you know what fuel pressure you are getting? Could actually be alot of things, gonna need some more info. But see what fuel pressure is under boost first, and see what volts you're getting to the FP

Is your IC hoses all clamped strong and no leaks in them? and is there a loud sucking type of noise when you get to the 10lbs?
