Timing and boost are inversely related. You run more boost with less timing and vice versa. 11.5 degrees of timing in your "old" logs is actually very high for a 91 map, but i suspect thats just because your boost was only like 10 psi in the upper RPM. You typically only see that much timing in ethanol or race gas maps when you are running high boost.
Your IATs are insanely high in your "new" log, especially in 4th gear, so i am not surprised at all you can't hold timing. I wouldn't even drive in boost with IATs at 150F!! Your IC is undersized for what you are doing because you get 40F IAT rise in 2 gears.

Apparently I did size too small on the intercooler.. I only spent like $350 on it.. I wouldn’t have known to look at the IAT’s if it wasn’t for you. So thank you for that! You think I definitely need to buy a new one??
here is 2 more logs I decided to try the multimap stage 2 93 this time. These logs look cleaner than any of the other ones.. holding better boost than the multimap stage 2 91, and holding incredible boost compared to the version 7.1 stage 2 91 bm3 tune.
I think the timing looks pretty conservative on these 93 logs too right? I should be able to run these safely?
