I was at a diesel rally in Bakersfield last fall and this graybeard walks up to my 6.7 Powerstroke after hearing it idle. He points at my EGT gauge and says 'You put that probe post-turbo, you're reading happy numbers, not real numbers.' I argued with him for five minutes saying pre-turbo was too hard to drill. He just shook his head and walked off. Later that night I looked up the manual for my gauge kit and sure enough it said pre-turbo is the only way to get useful data for tuning. I spent the next weekend pulling the downpipe and redrilling into the manifold. Now my temps read 200 degrees hotter than they used to. I was basically guessing on fuel before. Has anyone else had to eat crow after ignoring a veteran's advice?
Back in 2015 I bought a bulletproofed 6.0 F-250 from a guy in Spokane. It ran fine for years but I always had that nagging feeling in the back of my head about head gaskets and EGR coolers. Last summer I found a clean 1996 12-valve with a manual trans from a farmer in Yakima for $7,500. Made the switch and honestly I don't miss the Powerstroke one bit. Anyone else make the jump from one platform to another and have regrets or relief?
I've been chasing fuel economy on my 2001 F-250 for about six months now. Tried a different tuner setting last week on a run from Austin to San Antonio and held steady at 65 mph. Hit 20.1 mpg on the trip computer when I filled up, which is way better than the 15 I was getting before. Guess those injector o-rings I replaced actually made a difference after all. Anyone else seen a jump like that from simple maintenance?
Looking for some honest opinions on 5 Star Tuning for diesel trucks. I’ve got a 6.7 Powerstroke and I’m considering one of their tow tunes. Not trying to roll coal, just want better driveability when I’ve got the trailer hooked up. Anyone have experience with their diesel calibrations?
