[QUOTE="03' White Snake, post: 17008014, member: 51916"] 30 psi is too low when running. Bump it up to 40. Post some pictures of the engine how they ran the regulator and lines. I’d like to see the vacuum/ boost lines too. If you have a hand vacuum pump, you can plug it into the line that comes from firewall on passenger side (this isolates the engine vacuum harness, need to pinch off the vacuum line from rear lower intake too). Pull vacuum and see if it holds. If it does not then you have a vacuum leak. Also for giggles, check the maf is plugged in and the wires are not messed up or pinched. [/QUOTE]
