I think something might be up. Thats also with my boost controller (hallman) cranked all the way up.
I have no boost leaks as of my last test, which wasn't too long ago. Im thinking it may either be my boost controller, or waste gate actuator. Once I get my map sensor installed and logging I will see if everything is okay and start trouble shooting from there.
Enough off topic though, those are some seriously impressive times regardless of altitude.
