? about my boost

k im only pushing 8-10 10 at like 4700-5000 rpm's what could cause lower boost levels be sides ic tube leaks
 
Belt slip, worn or poorly sealing bypass valve, multiple boost leaks from vacuum lines, less restrictive exhaust or an inacurate gauge.

Yeah, old belts will slip. Vacuum leaks and just the age of the car. Our cars are anywhere from 12-18 years old and you can expect the blower to wear out due to age. Its normal for a stock sc to push 10psi, my old auto sc only made 9psi on a very cold day (stock).
