sounds like it's fueling fine... the 366 spring does make the governor more snappy... did you look into rack travel like RSWORDS had suggested? and by temp you mean engine temp? last i knew you didnt have a pyro... could it be a shut down solenoid problem? i know the same thing can happen with the P pump... the fuel shut off gets stuck half way. just enough for it to run but it's nutless... read around and see what it takes to turn it into a manual shut down set-up. i've heard for some reason the IC'd engines when you start increasing pump pressures the shut down solenoid goes out on it...

 

Yeah, I'm talking about engine temp. I don't have a pyro yet, it's on the grocery list. The weekend is almost here.....after I get hay(gotta test out the new flatbed) I'll start tinkering..........

 

sounds good man... sorry we haven't found anything conclusive; as i had stated before at this rate by the time you figure out why it isnt boostin like it should it'll be a running SOB
