How to find good quality gas?

[Christopher Léger]

If you're using that log as reference, I'm seeing 17-18 peak PSI. That's map 3 IIRC. You're also seeing ignition values starting over 10 and peaking over 15. I'd call that a good run.

Us Canadians heavily question our gas quality. For comparison, in 4th gear WOT under Map 2, I was typically getting 3-5 degrees ignition advance, not 10 to 15...that was on supposed 94 octane gas. Similar story with Shell 91 octane which is supposedly the best we have. I might have had a "slow" Stinger but my fastest runs on Map 2 produced a best of 13.19s 0-60 @ 2200FT and I never saw a 0-60 in the 4's, EVER, always in the 5s.

Quebec... I managed to get peak boost 20.3 psi on map 3 with 13-15 ign with shell 91 + octane booster 9points. Ran 4.450 for 0-60 and a 12.650 for 1/4, i didnt even use LC too.. you should try it sometime
