[QUOTE="B E N, post: 1638600, member: 33355"] 91 should be fine. I don't tow with mine so I haven't been able to log it. I have a couple of idea's for you: Open up the hood vents a bit, they have some slotting on the bottom but there is not a lot of room for air to escape with the skid plates etc. It's a nearly free mod and I really believe it will help. This will let water in when it rains but based on your location I don't think that matters much... Switch to a 170 or 185 thermostat and have your tuner set you up for it. Stock is 205 to help with economy and emissions. You may be able to keep enough timing in the truck to keep the heat down, it will give you a little more breathing room as you start to heat soak as well.
