Good evening gents.
Today was my first day towing with the new mods. I have a 2001 F350 longbox crew cab. I tow a 14' tandem axle v nose trailer weighing somewhere in the neighborhood of 7-8k lbs loaded.
My mods thus far are :
Air Raid cold air intake from DP
(I liked the setup it had for the battery)
4" straight pipe exhaust
Hydra tuner using basic tunes in the library
Everything on the truck is stock other than that. She has 300k miles runs like a top, and ate 12k in work last year (Ford rebuilt tranny, leaf springs, full front end rebuild, and the list goes on)
So my results for today were mixed.
Towing on fairly level to slight grade on the Interstate 70mph I was averaging
7-800 F EGT
180-210 transmission temp
I realized later on my transmission temp sensor wire was pretty close to the manifold and I think that may have been playing with the temp reading for that. I'll zip tie that in a better location tomorrow.
Now for my concerns. I understood I might get some turbo flutter due to the chip. It is pretty bad when it shifts gears and flutters quite a bit. If my turbo is not bad I'll be adding a wwII onto it. Is 5-7psi boost normal when cruising at 65? The highest I've seen her go was 20 psi
and thats when I'm really pushing her. What is a normal transmission temperature when towing? I am also noticing a grindy kind of feel when I'm not accelerating hard but still have a little pressure on the pedal. I think I have a bad axle u joint and attributed it to that but maybe I'm wrong? Lastly when accelerating with some boost is it normal for her to switch to 2nd gear and loose boost pressure real quick and lag a bit taking off in second?
So please read this and give me any pointers or observations you experienced diesel motorheads care to disclose. I would definitely appreciate your wisdom.
