alright guys i just sent my eaton off to steigmier and i am wondering where the heat comes from. i want to run a stock upper and 8 pound lower. my question is does most of the heat come from spinning or when the boost builds up, probably both but which one. right now i have a jdm long block with a 6 lber and only showing 12 lbs. Before i got the long block i seen 14 and 15 psi. just trying to get the boost up a little before i go to the tuner without pushing to much heat. i know boost aint always good but i love it. lol
