so this is what i got i have a 93 wagon sport..... when i test drove the car he only boosted 5 Psi.. guy said it was from the O2 sensor, and the way the winter fuels go in to the engine..... Yeah okay dude what ever so i guessed it was a vacuum line... haven't found one and then i got upset one day because i couldn't find anything.... so i just unplugged the wast-gate and the boost went up to 15 Psi which was nice tell i hit fuel shut up... so the Q is any ideas on how to fix it the right way and when its fixed how much boost can i put in to the engine to be in a safe rage?

-Well it depends on what turbo your running, but the cars stock ECU will only let boost up to 12-12.5 psi / fuel cut. You would have to run a fuel cut defender, piggy-back, or stand-a-lone to get more boost. TD04 is good up to about 16 psi and is a decent upgrade from the stock VF11, vf39 you'll end up maxing out your MAF, anything else is almost pointless unless you go stand-a-lone.
