[QUOTE="footlong70, post: 1129566, member: 8456"] It has nothing to do with the tires/gearing, something else is wrong. 3k weight trailer is pretty well a joke for the 6.4 on a 310 tune even with the tires. That kinda boost constantly without pulling hills or extreme wind is usually related to a VGT issue. Whats back pressure reading throughout? Is it changing consistently in relation to the boost? Almost sounds like a bad/unplugged BP sensor or froze off BP sensor tube. The bp sensor is the primary sensor used for controlling the VGT position. Been there many times making 30-45psi boost on flat ground, completely empty just because of a froze off sensor. Also just for giggles, what gear were you pulling in? 4th or 5th constantly? Was the converter locked? [/QUOTE]
