just did a simple mod and WOW!

If that's the case, something else isn't letting it build boost. A broken hose, cracked intercooler, bad CBV valve, vacuum lines, etc. That gauge on an 850 should pin itself to the right under full throttle at ~4000 RPM, but it's just a guide if anything - not accurate at all.

Back it off and get a boost gauge before playing with it like that. You shouldn't be hitting full boost before 3000 RPM or more. The engine internals just can't handle it.

set at 1.8-maybe a fuzz more.,and now that i think about it,it does go just a tad more,more like 3/4 at wot around 35-4 grand...i guess tomorrow i will put it back, i dont want to mess something up....oh well.

Stock. Like most of us have said, something isnt right. If you get a boost gauge, you can monitor vacuum at idle, which will help find the problem.

Don't turn it all the way back, do a little research and put it at stock (3.5 psi?). Then look around in the engine bay. Holes in inter-cooler lines, etc. Is your CEL on?

i have no dash lights on and i sprayed statrer fluid all over the motor and it never died or raised rpms.....everone says it should be a fuzz over the white line fatory when at wot....

Woah, wait, what? Explain more please...

[erikv11]

spraying starter fluid is a standard test for vacuum leaks. If there is a leak then the fluid will get sucked into the intake and burn, raising RPMs.

Yes, something is preventing that. If you leave it where it is and fix the problem, and take it for a drive, very bad things will happen. So return it to stock, then investigate whats causing boost problems.
