You have a good point - fuel and boost make all the difference. My run below was with MOSTLY 104 octane. No adjustment to boost at all - 15 PSI per the factory gauge (no aftermarket boost gauge at that point). BFG DR's. Walbro 340 with hotwire. Old school ram air CAI. Bosch 237 FPR @ 43PSI line off. The car ran absolutely terribly with pump gas. The race gas made a big difference.
I have no experience with alky and am definitely not an expert, but the OP has a few key components that I did NOT have on my run that might allow him to run a little more boost - RJCPP and the upgraded IC. That's just what I was thinking. If he runs the alky and has no KR, then I say turn up the boost slowly and sneak up on the tune.
The question I have is - if you have alky, why would you NOT want to use it? Especially since your chip is burned for it. It will make a big difference on how much boost you can run, and boost is the key to power.
