I played with the vacuum gauge and idle a bit more today and got it closer to 19" while idling in drive. Very high but I don't have power brakes so maybe that's why? I made it the 60km journey today and it really has a hard time on the few hills and accelerating between 40-60mph. I'm convinced it's the low PV as the lowest I observed the vacuum at was the 10" line. So I'm going to hunt down a 10 or even 10.5 tomorrow and see what that does. Seems like a big number but it's just a bit above holleys recommended 50% max. Either way, once the turbos on I might need the extra enrichment.

I'll let ya know if I go too rich again.
