Works as expected then.

How much timing that can be run on boost safely depends on the car and conditions.

Again, the C2 Turbos run about -18 to -23 depending on intake air temps and US 930s run about -16 to -19. You might be able to run more under some situitions. As you do not have a boost retard function I would not exceed this much without good info to the contrary.

If me, I would add MSD with boost retard. Set timing at about 33-35 deg with vac line temporarily disconnected and set the MSD boost retard at about 1.1 to 1.3 deg per pound of boost and fine tune from there.

Or, convert to a US dist.

There is info that some are going more aggressively than this without issue.

Please verify above with a real expert.
