If things go right i'll be headed to make the 50th pass on the coupe in the last 7 weeks. Also this will make over 70 passes total for me so I'm getting the hang of it. I'm not sure what the deal is. I still have the TC intercooler, I'm at 14* base, and 18 psi. I'm a little amazed. I'm running 93 octane w/ knock disconnected. Fuel pressure at idle with the vacuum connected sits at about 35 psi and the A/F never goes into the green. I've tried to keep it 2 bars in the green so I'll probably turn the base pressure back up tomorrow. (yeah stinger I know but the wideband isn't in the budget just yet) I've driven 120 miles now and haven't heard the first sign of detontation. Is that normal? lol I might switch back to the volvo cooler tonight and try it again tomorrow. What is considered the correct procedure to setting the kirban AFPR? with the vacuum unhooked or hooked up?
