might stop being lazy and lock the baseplate instead of just disconnecting vac advance
that might stop some jitter. I should of done it when I did mechanical advance :shh: :shh:

still having charge problems, might be time for a new battery and alt upgrade
also chatting to a guy about getting it on a dyno for a bit to make sure I'm not completely plucking it up

dyno is a must for doing spark accurately, well worth it.
I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.

Old mate seem to think differently, and is reluctant to touch it as he feels it will be to much work for a very little gain. Said I would be struggling to do any damage if I'm not dialing crazy numbers.

Yet a gemini but that tunes on the mainland said to be very careful as I will easily break rings

Only other option I have local will probably do it but going to need deep pockets

I'd recommend the update to a pulsar alternator with built in reg. Its not a hard conversion and the gemi alts are old and nearly all dead. I have about 3 dead ones and no live ones at home, and did the pulsar alt conversion on the new track car after I got it and found the stock distributor was already dead.

The EFI conversion will provide gains, but not epic gains (until you stick a snail on it, 2 bar map and larger injectors). But will provide great reliability gains.

Wasn't looking for big gains going EFI
But 80% of any gain I will see will come From timing.
He was more referring to dyno vs seat of pants tuning.

And the pulsar alt was the plan just haven't had time for a wreckers run, not till this arvo

Well charge problems sorted and its a new car
Runs like a pig when cold but I haven't even played with any of that as yet.
Made the trip to and from work today ok still yet to look at logs. The few times I glanced over at it on the way to work, all looked good
