boost gauge problems???

[splitsecond03]

the boost gauge reads at 20 psi at full throttle. i have adjusted the boost controler all the way out and all the way in. no matter what i do it reads 20 psi. is it normal and its an autometer boost gauge.

it is if you are reading 20 lbs of boost

assuming your 'boost controller' is MBC(manual) I would say you have it hooked up backwards; this would cause it to never open the wastegate therefor running full boost all the time.

Also I think I've heard about some MBC getting stuck open, that could also be it.
Goodluck

are u sure u are not looking at that vaccum side of the gauge. the needle usually rests on around 20 to the left at idle. boost is the right side of the guage.
