Same logic with meth safety 2?

I read this in JB4 ISO 27.8 meth safety changes thread:

Option 2: ... Note that while we don't suggest option 2 due to its non-integrated nature the benefit here is going to be quicker boost response. When you decide not to worry about spool up knock and whether or not your methanol flow is sufficient for the tuning the car can feel more responsive. It's a bit like burring your head in the sand but for those running E85 + meth its less of a risk than those running pump + meth.
I could try 93+meth for less risk.

Log is looking good to me man! The little throttle closure is because your boost went over target at that moment. So throttle closed a bit to regulate boost.

Ok, now it's clear

I did another log with 75 additive. Boost is near to 25 psi and timings seem good. I am not sure about fuel pressure high. Do you think I have margin to raise more boost?
