Well I have over 9,000 miles on the truck now change the oil out after 5,000miles.
The truck went from a 16.5 in the 1/4 mile to a 14.13 best so far. I have driven it to 2 race events one over 240 miles each way with no problems.
I have made several trips to Portland and back now and the temps even in 90 plus weather and A/C running and only here the fan come on after a hill.
I have to roll into it a little more to get it going but after you are at freeway speeds it dont take much to stay there.
EGT's are higher in cruse mode but I expected that with the lower rpms.
EGT's even up a good incline with my foot matted stay well below 1,250.. I am still getting around 16.5 to 17mpg on the freeway but around town its pretty crappy.
I am thinking of going a little tighter on the converter this winter. The truck really pulls hard from 40-mph to about 90mph like crazy onramp speeds.
I enjoy the power level I am at now I figure around 400-425HP.
No leaks its quiet and a real sleeper..
First 1/4 mile run 14.13
