Timing

[Lonestar10]

Thanks for response. ive just been foolering around trying to adjust for my fubar 4.5wedge cam instead of the 4 it was suppose to be and also chasing other demons right and noticed as i went negative in SOI my boost came up higher in pulls but power did seem to go down. my EGTs stay around 600-625 on flats cruising and only go up to 700-725 on a long hard pull "sensor is after turbo in 7th injector pipe".

another thing is the difference in power between say 20-25lbs of boost and 35-38 seems negligible to me out of the several trucks ive driven and at 20lbs the lie o meter is already at 2.5mpg and doesnt drop any further the higher the boost goes.

500HP Paccar MX13, 2 450hp 13L MAXXForces, 1 450hp detroit 15L, 1 550HP 3406 CAT this truck/engine combo feels the slowest/gutless of them all

the 3406 CAT i pulled 100-110k lbs gross of grain and that truck would walk all over this one and still get 6.2MPG all day driving 70-75MPH where i drive 65-67 now.

so its pushing me more and more to go see the masters to find out whats wrong with her. i love the truck and the engine for me works for being able to work on it myself but im getting to a point where my skill level isnt enough to do her justice as all the parts ive replaced so far havent seemed to make a dent even though there have been issues with all that ive replaced.
