A PS2 with any E30-50 mix really needs a Stage 2 HPFP to not have any issues.
I don’t quite know the differences bn the 2H and 2+ maps. 2+ targets 20.5-20.9-psi and I can hold that pretty consistently with my setup. Power just drops off above 6k bc the Stage 1 turbo can’t flow enough to keep up.
If your Stg 2H maps are anything like the Stg 2 93/E30 maps for the M2 (~17psi), I was never able to really maximize the Stg 2 E30 map bc my stock HPFP was weaker than some. And, I found Stg 2 93 needed octane booster or a cpl gal of E85 in the summer to keep timing clean, so that’s what led me down the Stg 2+ E30 path.

Thanks for the info! Always a desire for more power! I assume you're running a Dinan turbo and a dorch stage 1 hpfp and also I don't believe a lpfp is needed for E50 mix correct? How's the drivability with that much power? I would love to put a bigger turbo in one day but I'm concerned with reliability and daily drivability
sorry if it seems like I'm shooting off a buncha questions you seem very knowledgable on this kinda stuff
