It depends on the chip. Check the instructions if you got any. Most set around 42 psi with the vacuum line off.

you will want to take the vacuum line off and at Idle, adjust for 43 PSI. as you put the vacuum line back on, it should drop down about 5* psi. the main thing your looking for is a constant increase in pressure as boost builds. 1 psi fuel pressure per 1 psi of boost.

The regulators need rebuilt after a few years. Rebuild kit under $30 delivered. They cause fuel pressure to not rise one to one when they need rebuilt.
