Ok heres the problem. My supra doesn't boost up at low end power. At high rpms it does. I have set my avcr to 20lbs, but it won't go past 14 no matter what! Could it be a vacumm leak? blown or about to go turbo(s)? Also what causes me to have light smoke coming out from the exhaust? I have the apexi exhaust with no cats! I know that doesn't help.
All i have are the hks super sequential, greddy intercooler, apexi avcr, safc. Any info would be great.
