maybe you missed this....
Telling him to advance his timing is not decent guidance.
No I didn't miss that, but it's det he should be monitoring, even if the fuelling is spot on there are so many other factors (as I mentioned above) that can cause it to det.

The factory unmolested timing map must reduce timing based on boost levels.
As factory was limited to (8psi?) does the stock computer reduce timing at higher boost pressures - or does it reach a maximum boost retard at 8 psi or more?
Any idea what total ignition timing is at 1 bar and 12 degrees (factory setting)?
Does the factory Ford computer change timing vs. RPM and Boost?
A factory map would be awesome to see.
Cheers
My understanding is that beyond factory boost no it does not pull timing, you have to manually move the distributor to retard it for higher boost settings, some chips have a revised spark map but most just remove the boost cut and I do not know what the factory MAP sensor reads too either.
