i'm running 37's on 4:10 gears.

i'm doing 1900-2100rpm at cruise(63-65mph).

i dont know much about timing, i have a diesel guy that i like and he helped me with a spendy tool to check and adjust mine, it did seem to change the sound a bit and the performance eh? hard to tell.

ive got the fuel screw right at the point where i get a puff of smoke on hard throttle. but i dont yet have an EGT so i dont want to fiddle with it too much.

i know it can get better but i'm quite happy with mine, i wonder where yours is falling? i cant imagine your 60 is much heavier than my 55, its a porker.
thanks for the data points. a 7% grade with a trailer, still in 4th is awesome, i will take that! i kind of expected that kind of diesel power.

was curious what your boost looks like at cruise? I only get like 3- 4 psi, seems like it is too low. I want to try and a 4bd2t turbo, i am hoping it is a easy swap. seems like perhaps my turbo is not generating enough boost, which results in low power, rich fuel ratio, and high egts?
