Have some questions for the N55 guys running Meth+E85

Hey guys so I’m currently struggling with a setting or mixture. Im running 70/30 Meth and water VP M1 and 60/40 93/E85. I’ve gone back and forth so much with burger that I’m willing to beat my head against a wall. I’m running a JB4 stage 2 with flex fuel kit and the bmws meth kit.

Other mods
VSRF down pipe
VSRF charge pipe
K&N intake
Custom 3.5 inch straight pipe exhaust
Also a pwg car
Forge blow off valve adapter


So my question is did any one see large drops in boost pressure my car will see about 18/19 psi then drop to 15/16 then spike back up.

Thinking about stacking MHD or Bootmod3 with the JB4 but nervous seeing that there’s no one in the DFW area that’s doing custom Dyno tunning or installs. With all the issues I’ve had with the JB4 it just sounds like another headache. Also it’s probably what’s keeping me from ordering the PS2 for my car.
