so i FINALLY got out of town this past weekend. Have not had a vaca since Feb and was going crazy from the heat. Loaded the trailer up minus toys (no tracker or sand car), loaded momma and brooklyn up and headed off to meet my buddy at an intersection just outside of town. he has a 2012 dodge dually with a small tune and deleted. hes the one that basically drove me into hopping the limo up cause he kicked my ass in an old 12v of his years ago in college. Anyhow, he has a 38ft trailer very similar to mine and was only carrying a golf cart. We head up the hills and its really the first time ive gotten to compare my truck to someone else towing similar. first two big hills out of phx, truck is staying semi cool in 95* heat. peaked 235* on coolant at the tops but i was getting drug down to slower speeds and acceling back up to 60-65 pretty quick. I would pull away from him each time, then i got cocky....
last long ass hill to flagstaff from camp verde, i let the truck just lug along in 5th gear pulling the decent grades before the big hill instead of trying to keep it cool and slowing a bit on them. totally forgot there was no downhill before hand to cool the truck down. went into the hill with 240* oil temp and 210* coolant. When oil starts creeping up beyond 240*, coolant starts going with it. had to drop to 50mph and 3rd gear at 3k case i was at 240* coolant and 260* oil...... and here comes my buddy..... he cruises right around me at about 65 and a brand new dodge with a little smaller trailer follows suit. i was PISSED! literally cruised the rest of the hill at 50mph and 240* coolant temp but i started pushing the bitch half way up at a little plateau to see if i could maintain 60-65. no dice. actually hit 250* coolant at the very top of the hill.
I told the wife, "thats it, we are buying a new truck. Im done with this thing". :rofl: She gave the green light..... after my daughter starts preschool in a couple years. :baby:. So i decided id try something i never thought id try or even wanted to do in the last 7 years.... TURN THE TOW TUNE DOWN IN POWER. yes ladies and gents, its a sad sad day. i spaded the old girl and dropped power out of it to see if i could get temps to stay down and just hold the bitch WOT up the hills without worry.
Dropped my tune from 1150uS (im on 100% overs) to 850uS and about 10* of timing at 3250, about 8* at the cruise area in 2100-2300. There was really only 1 main hill on the way back down but its not nice.
Finished out the weekend in some beautiful weather and headed back down with the masses. leaned into it on the high way and she still gets up and goes more than i expected. Get all the way down to the hill that now heads south out of camp verde (there is a hell of a grade going out of camp verde in either direction). traffic is f**king nuts at this point. im stuck to 40mph up the hill with oil around 235* and coolant at 210*. it stayed that way till we hit the 3 lane and i hammered down to pass another dmax and some truckers. went from 30mph at that point to 55mph and by the top, i never saw over 235* coolant with a/c going the whole time (on the way up, i turned the a/c off at every grade to keep heat soak down). Oil was around 245-250 max. i was pretty damn happy with that. Even got to race another loaded up LML up another small grade before heading down black canyon city hill. wizzed right by him and his was singin!
So anyhow, i just flat out cant keep her cool and im tired of testing my nerves and head gaskets. Im going to pull a bit more out of the tune if the truck will still run right and may even drop back to stock injectors. May play with timing some more too as its pretty conservative. Get her to cruise the next couple years without issue and then either buy a low mile L5P or see whats out then. after towing in that dodge, i know i will be happy in the GM. Ill keep the limo and keep it as a toy or occational tow rig, dont really know yet but my wife and i both agree i cant sell it.
