could we run the bm3 stage 2 93 or race map with 50:50 meth injection and 91 fuel?

BM3 suggested race gas map with 93/91 octane (either works i guess) on 100% meth. E30 map has too large a fuel scalar, the meth sprayed in will cut too much actual fuel from HPFP. 50/50 with 91oct might not yield 100 octane or more. i hear 50/50 runs in the high 90s in octane. Just that ALONE wont replicate race fuel. 100% meth (110+ oct) with 91/93 should do the trick theoretically

Damn! Not too shabby at all. I assume your spraying via the bung on the charge pipe? Which charge pipe are you using?

Yup I am using the bung that came with my FTP Motorsports chargepipe. It was actually hard to thread in and didn't go in as far all the way in as I would've liked.

Also for boost read I cut a hole in the silicon hose connecting the two chargepipe pieces. Then installed some boost tap hose port from Nitrious express, I think. The tap was very wide in dia so I had to get a hose reducer to go from that tap/hose to a small hose for my boost input on the controller.

Rad, its impressive to see timing relatively good across all cylinders.

Can you comment on any potential pickup issues with the system when the fluid gets low and you're making a lot of turns? Do you think the fluid can slosh around and cause the pump to suck up air? I'm probably over thinking it but want to cover every angle before I take the plunge and order a bunch of parts.

I had that worry actually but as long as the fuel tank exit is above the pump input, all should be good. The air bubble will just pop right back up once the liquid is back covering the fuel tank port again. On top of that, I use the nozzle #4 and the amount of fuel consumption can't cover that 1ft line from the tank to the pump. And if ur that low on fuel, don't be gassing it so much haha. I just try and fuel often just Incase but I get low with no issues. Snow advised me on those notes above.

Heres another question for you... How has Cary setup the tune with regard to meth safety? Are you super on top of keeping the tank full? or is there room in the map to pull timing once you're out of the juice?

The tune proactively cuts timing if the octane isnt there. But when aggressive that may come with misfires and safety concerns. Honestly, there are no true safety nets with the custom flash and plug in meth kit.

Snow performance stage 2.5 kit comes with alarms though. Low fuel warning, leak warning, kinked fuel line warning, or flow issue. also it has a check valve which ensure flow at all times.

That along with the minor adjustments the timing has available, i think is enough to keep your engine safe and warn your when to let off the gas. I do stay ontop of my fuel and by 5 gallon pails. I go though a 5 gallon pail in 2 months i think. I have NEVER had a misfire or knock.
