Boost targets are fairly conservative. Two timing drops and high WGDC is likely due to you're super high IATs. Get an intercooler.

Agreed on the above. You need an intercooler in a major way OP. The timing drops aren’t too bad but it’s going to be hard to build a strong curve with 93 octane and those types of CATs. Car feels weak because the advance is messy. Go FBO, add in some octane, you’ll be fine. That’s a very conservative boost curve as well.

Map2 is very conservative and your IATs are very high. FMIC and maybe a 2-3 gallons of e85 with map5 should clean up that log.

Yup, you'll need a FMIC and more octane either through e85 or meth to clean up that log.
