Engine/Transmission (1998.5 - 2002) Any problems with comp always on 5x5?

[TBrandes]

Other than decreased fuel mileage is it bad to run the comp on kill mode all the time. I've had it for a few months so I'm not "stomping on it all the time" like I was when I first got it.

Basically, with sensible driving is it ok to run like this all the time???



Thanks.

I don't see why not... mechanicaly injected trucks are set on kill all the time

I would take it off "kill mode" when you hook up to a trailer. EGT's will go through the roof on 5X5 towing heavy.

forrest is right. we just towed a parachutte of a trailer and we were playing with the comp on 3x1 then to 5x5 we noticed a decrease in egt's. So we ran it that way the whole time, we weren't towing very heavy but the trailer was a parachutte, through some pretty hilly terrain, cruise set at 70 not a problem.



On second thought i would probably turn down the low boost fueling just to try to keep it clean on the slow take-offs.
