M8 Race Gas @ low elevation (Issues)

[Mod800R]

hey all,

awesome to see a forum dedicated to twisted customers!

Am looking for a bit of setup help for this years setup, am from newfoundland canada running a 09 m8sp with ras gas extreme kit with a 150 Cat race team hillcross kit. 9 psi with straight 112 race fuel

1500-2500ft, am really interested in shains boost juice, as race fuel here is brutally expensive! would it best cost effictive @ my elevation?

how much boost can i run on straight 112 octane?
how about a 75% 112 to 25% 91 octane mix?

also, what should my afr's be at idle,mid throttle?
could anyone help me to get a decent baseline settings for my attitude box?

mine is 14:1 to 15ish at ilde, and 13ish mid throttle, and 11.8 wfo...

with the afr's as it is it is really sluggish, and does not pull hard...7500rpm max

what should my rpm's be at? 8000?

also if the seal for the pto side of crankshaft was leaking air, will the efi compensate with fuel, or would it have poor idle and rough running like carb sleds?

am thinking i may have a crank seal issue or damaged reeds...gonna tear into that tonight!

thanks for any help guys
