Update on the situation:
I re-installed my Blixxton and changed my fuel filters and I have absolutely no change in the situation.
At maximum, my boost pressure is 29psi where as before it was pushing 33psi sometimes 34. The condition that I experienced at the intersection a while back doesn't support that it has a boost leak however I'm not ruling out that possibility, that's what I'm going to look for next actually. That day, I very clearly felt the throttle go to about half throttle and suddenly back to about 95% throttle without my foot ever coming off of the accelerator. This has me thinking it is a issue inside the electronic system of the fuel control.
I did verify that my throttle pedal position sensor is working correctly. That's about all that my tooling will do unfortunately, I can't read any other ECM data regarding fuel control. I wish I had an actual VMAC2 reader to help the situation, my local mack dealer doesn't have one anymore
