I have a 95 k3500 dually with new Diamond Eye 4" exhaust, walking J chip in computer. manual boost control, snorkel removed from air cleaner, inlet in air cleaner box opened up, high flow water pump, dual stats, late 6.5 fan, HD fan clutch. I pull a 28 ft Pace American trailer. It pulls ok in cool weather, in hotter weather with the AC going the truck is a dog.



Is it normal for these to drop off so much in power in warmer weather? Is there much I can do to help it?
