thanks for the quick response. and you're right. i was confusing open loop fuel with open loop boost control. i may try tuning with closed loop boost since you said it's reacts to different ambient temperatures better. when you use closed loop boost do you have to calibrate the map sensor?

i mean, how does the UTEC know which boost values to reach and then start leaking pressure once such a boost value is reached? i don't recall there being a place to enter in such a value. basically i want to learn exactly how the closed loop boost control system works in a UTEC so i can understand it and tune it. thanks for your help. i will be trying the GM BCS soon with a cheapo MBC. i'll post up my results when i do.
