Thanks for the reply
I have a hood mounted Ken Bell FP gauge and fuel pressure is a rock steady 43psi @ idle and rises steady 1psi with boost. I've been keeping it to around 5-8psi for obvious reasons, so 48-53psi with light pulls. The gauge shows no drop, no interruption. I have a new pump and hot wire kit on order from TurboTweak since the XP pump is over 20yrs old and I've never put in a hot wire kit, but I'm not expecting this to be a fix since I'm not seeing any issues at the gauge.
The plugs look a nice light brown (I had them gapped @.032 I just squeezed them down to .024 but haven't driven it yet).
The car has a new ccci module and coilpack (tested ok caspers tester) wires are fairly new MSD 8.5mm.
Yes I'm seeing 2deg or so of retard on the scanmaster. No data logger yet, guess I might have to get one!
O2 volts are a nice ~780, compression tests 150+/- 2psi, I've pulled the valve covers and I'm not seeing a dead lobe (didn't measure just observed).
