Yeah, not fun with a 93 tune either. If you drive the speed limit, the mileage isn't too bad, but up at 80 and about...

 

The cam I had, currently in goshawk's truck, is a 2000 vette cam pn 12560968 with specs of 198/207 .500 115.5
It seemed to do well in my reg cab but I also had a converter, headers and was able to dial it in tunning wise. It dosnt seem to be doing as well in John's ext cab mainly because I dont have the tunning freedom I had with mine as well as it being a heavier truck. I think if we could advance it a bit in John's truck, it would make a world of difference.

 

i have 31" tall tires. so i am running at around 2200 or 2300 rpm at 70 i think. i do believe at 75 i am running at 2500 rpm. i haven't noticed my mileage dropping off.

kenny, when ever you feel like cracking it open again, i am game.
