i have realized that there is a window of best performance with the truck. for instance i did a run yesterday the temp was 46 degrees and very humid i ran a 4.8 with little to no gas in tank road was flat and truck was at normal operating temps. this is the same stretch i ran the 4.4 a week or 2 ago. This morning before coming into work, on a full tank of gas, i ran a 4.5 in the opposite direction as last night and opposite direction of my 4.4. I have been running in sport mode, launch from idle, and i paddle shift. transam wrote in a thread the RPM's he shifts at and i have been following that. 1 gear shift at 5200-5300. also i only put shell 93. i have noticed a HUGE difference in gas.
