I'm new to this site needing some help with methanol injection I used to run e85 what is no longer available near where I live wondering timing and boost levels on e85 can I still run the same 100% meth injection I have a 5.3 that was bored to 5.7 I have a s475 non intercooled running a truck intake and using megasquirt ms3 71 Camaro 400 turbo 9in rear end e85 I run 18 lb of boost 16 degrees of timing just wondering would meth and 93 and can I do it with a single nozzle or do I need dual nozzle to get me that closeI will I need to back off the boost and timing thanks for any help

Non intercooled?

No. You'll need about 6 degrees less timing to start and then creep back up on it.

Agreed, less timing and you gotta be careful with 100% meth as it has a super low flash point. At 15psi I'm at about 14-15* on 93 pump with wiper fluid, on a mostly stock 5.3 (ported heads and a cam) but I also run a FMIC so my IATs are around 100-120*F on a 90*F day in boost closer to 90-100*F with the meth on. I usually see a 10*F drop in temps during a 3-5s pull some of the temp drop is still going down coming out of the pull.

Keep in mind you won't have the benefits of alcohol until the methanol starts spraying so you don't get as much low-end benefit.
Watch those temps, EGT, and AFR like a hawk.
