Damn STS Buzzer
Damn STS Buzzer We'll I just put in my T76 and turned the boost up to 12 lbs. My tuner decided to raise the rev limiter to 6700 to help keep in the power band with the bigger turbo. After we got it tuned I took it on the road and noticed the STS buzzer was going off at the higher rpm's, what boggles me is that it just started doing it once we turned the boost up? Does anyone have an idea what the problem might be 
At the return pump, there is a Hobbs switch. Take the rubber cover off and ther is a small dime size plug at the top. Inside there is an Allen head fitting. Get an Allen wrench and turn it clock wise one turn. Go drive it and see if the buzzer quits going off. If not, turn a little more.

Hey there, don't mean to change the subject, but what kind of numbers did you put down with the T76? You're setup isn't far off from mine, I just don't have the fuel done yet.

It doesnt change flow.

How much power was that thing making?
