Cold Performance
I have been meaning to ask this one for a long time but with all the other details I had to iron out, it took a back burner.
When my truck first gets out on the roadway and climbs to 50+ it is wonderful. Then it seems to warm up and suddenly the speed drops down as much as the pedal that I now have pressed way more downward to keep the same speed up.
Choke comes to mind. Its dramatically different from before that point to when it seems to warm up.
I realize diesel tech involves air cooling, turbo, and blowers and such, but to me this is so rediculous that I have to ask if there is something I can do or disconnect to keep it running that way all day.
Its as if the block acuires heavy friction after a warmer temp.
Again, Cruisin along 1/4 pedal or so doing like 55-60, then Wham, it bogs down and I have to drop the pedal 3/4 or more to get or keep the same speed. The first mile or 2 are great.

Knowing it runs great when its cold, you still think its the timing ?
I remember touching on this before when I had a concern for the smoke.
I twisted the IP, and played around with the fuel adj.
I thought I got it to a happy medium.

Yep, my gues is the timeing is much too retarded. When its cold, the IP automatically advances the timeing, when it warms up it goes back to "normal". There's no such thing as a choke or anything else like that on a diesel. Not much else it could be that I can think of, unless the ip is failing and for whatever reason works better cold than hot.
Do you have gauges? If so, what are your boost and egt numbers cold vs hot?
good luck
