I will admit I do have a lead foot at times but honestly my main trip to work is at 4am so I am very gentle with the truck then as im halfway asleep still. Also was wondering wouldnt it be better to run an 89 tune instead of the 91 as if you use 91 even if you get better mpg it doesnt matter as you pay more for the higher octane. I have never used anything less than 91 but already putting 400 miles on my truck in the first 3 days has made me think a 89 tune would be best and a good 91 for when its a nice day out and I want to burn 80$ or so. Also I ended up getting the k&n drop in filter and will most likely modify the intake tube to remove the ridges and see how that works. Didnt really notice a difference yet minus my bank account being down 55$.
Well I found that whether I run 87 with stock tune, or 93 with 93 performance tune, the cost/mile basically evens out, I get better mpg with 93 but pay more. The benefit is the added power. I think with your hemi you are supposed to run 89 even stock right? The 93 performance usually gives the best mpg, but like you said you pay more. I think the only way to beat the cost/mile of the performance tune is to possibly run the mileage tunes, but I never even tried this.
