Alright, I have searched and have not found the answe. I have a 90, auto, 40k on rebuild. Upgrades are: true dual no cat exhaust, intercooler fan, 76mm c&l, aluminum intake pipe, 75mm TB, 5% sc pulley, 5% jackshaft, raised top, and a custom chip from Dave. My buddy installed the raised top when he was visiting and I was working. Said the gaskets looked good, even though I had a teflon set waiting. I was only getting 12-13 psi and power was down. So today I pulled the hat intercooler pipe and sho nuff signs of leakage. Put my gaskets in and re-sealed it. A little test drive showed pegging the boost gauge and good power. Spinning the tires again. So the question is, with these mods how much boost should I have? 15psi+?
