Thanks for all replies.
While at the dyno, I tried turning up the boost one full turn on my MBC and as we started doing the pull, as soon as the car hit 28psi, it started sputtering and missing. I figured my plug gap was too big, so I pulled the plugs and closed the gap, but that hasn't changed anything. On that pull with 28 psi though, power was climbing much stronger, I gained 20whp over my previous pull just at 3500rpm, but then it started to miss.
I ruled out, that missfire was caused by newly wired slimline fan (always on) drawing too much amperage and voltage through it, causing voltage drops and weak spark. As the result - missfire as soon as the car had some decent load and boost. I have disconnected the fan and it runs perfectly now.
I tried leaning the car out, but that yielded no power. Keep it mind, that 10.0 AFR's are on the gas scale and ethanol needs 30% more fuel to maintain stoich afr's. Ideally, I would like to tune e85 with lambda, but I have to learn how to do so first.
My trip to the dyno was aimed primarily to discover how good my tuning capabilities were and how much a car can put down with my setup. I wasn't looking for a tune, since I prefer to tune my car myself.
In terms of driveability, e316g is still a blast. Spools up faster than 14b and has tons of torque that literally sweeps you off your feet and puts you back into the seat hard. Great feeling!
I would like to say thanks to my friends who made this possible. Special thank you goes to Brian (archertsi) aka Byrdseed aka BSM. He has supported me throughout my whole DSM experience and I would never be making a 300whp dyno pulls if it weren't for him. Thanks, Brian!
