What do you guys with AVCS heads see for advance normally? I know it depends on that ECU you are using. I'm using an AH581 ECU with V8 RA heads, at low TPS and MAP I see 40 degrees of advance, that's as high as it goes. It then trails down to around 25 or lower at higher RPM. I haven't really pushed the car so it's not seeing more than 10psi of boost right now and hasn't seen above 6000 or so for RPM.
