well i just pulled our 4 nowmobiles an hour and a half from our house and had to keep it in stage 10 to pull any hills but the egt's were way too high sometimes seeing 1450. what'll cool them down a little more

 

If you HAVE to have your truck on stage 10 JUST to pull 4 sleds up a hill then there is something VERY wrong with your truck!! Considering your truck is rated to pull like 13K and 4 sleds doubtfully weigh even 4k with trailer!

The only way to bring down EGTs is change turbos, turn ADR down, or get water injection.

You still dont have a fuel pressure gauge do you?

 

no yet its on the way. i cant stand my auto tranny for towing but i grew up with manuals so that could be a factor
