A Few ?'s
I finally got the turbo in today 
and now have a few questions...
1. Does it matter what vaccume line I tee bov into? (same ? for boost gauge)
2. Why is it that Im running more boost (7-8psi) with bov hooked up, and less boost (5-6) with line unhooked..
3. I barely retarded my timing, and car ran soo.. slow, so I advanced it 2 degrees, (at distributer) and it runs good. Should I keep it advanced. Is it bad for it.
4. I dont have my downpipe made yet... Think that will make car perform better? (with the backpressure and all? )

Re: A Few ?'s
1. absolutely not
2. i have no idea, it would sound to me like it would work the other way around... who cares anyway 7-8 psi is fine
3. your dizzy should be at stock timing setting. I would strongly suggest retarding it instead of advancing. What management are you running? FMU, afc, crome...
if your rocking either of the inferiour.. back the dizzy off a degree or to (i.e. if you have a z6 15-14* base timing)
4. I reallly hope you have some kind of a dp. You had to have driven the car to make 7-8psi, and i wouldnt drive it with nothing at all off the exhaust housing. At least a 90* bend or something. But i guess to answer your question, yes, a downpipe will be a worthwhile investment to your setup

Re: A Few ?'s
yea, thats what I assumed.
Another ?... Im thinking "check valves" will help lower my boost pressure, but I think my chip is running off my map sensor, and that might throw it off under boost. Any thoughts.
