So on my way back from Idaho i was a hauling a 30 foot 10,000 pound fifthwheel with a pretty high clearance. I hit a headwind probably 50 mile an hour and i was running 92 percent throttle and 28 psi boost and doin 65. What kind of boost will these trucks take? and i havent installed my pyrometer yet and really wish i wouldve.
