ok, with the mods in my sig, what vacuum should i be pulling? i pulled 11 inches today at idle. my car is running pig rich too. my afpr doesnt let me go under 41-42 with the vacuum line off, whats up with that?? anybody else have this problem with their BBK? damn POS. with the vacuum connected it only goes down to about 38. I have a ton of popping in the exhaust at almost anything above idle. What should my fuel pressure be at at about 2000 rpms to 2500 rpms?
