i am in need of some serious help, truck is losing power as the days go by, already has new filters etc, clean air filter, the boost is there, blowing smoke like an edge ez, but with all boxes off, exhaust temp is higher than normal, has 50k miles do i need to adj the valves, and if so what is the sweet spot, i have a manual if that is what u guys set them to , truck is an 03 ho 6 spd 4:10s, twins, tst, ramifier, pusher pump, the usual, 60lbs on 4-2 tst only, with 1500 deg out of #5 ex port, not normal and i cant even slip my single disc clutch any more any help will be greatly appreciated... ..... :{

Have you tried an injector fail test? Do you have a ruff idle or knocking sound that isn't normal?

What kind of boost gauge? Mechanical or on the TST?

look for an exhaust leak between manifold to turbo and also between turbo to turbo, that will cause high egts and loss of power.

Maybe a cracked tip on the injector???

 

[Joseph Donnelly]

Injector needles and nozzles might have been eroded if you ran very high rail pressures for a long time--you would see low mpg and rough idle; boost hoses could be leaking--the one at the turbo is thin in the middle accordion part and could have worn through if touching anything; intercooler could have a leak.

truck idles good, no smoke, no exhaust leaks, drives like a normal truck, with all the good stuff turned off, has new fuel filter, clean fuel, maybe my tst isnt doing what is supposed to, i am going to trade tst boxes with a friend today and see what happens, i am going to run an overhead and set the valves at 10 on the intake and 20 thous. on the exhaust with a cold engine then i will post back later today with my findings, also, still throwing the usual p0336 code but dont think its the problem, my guages are autometer for boost and pyro, depricol for fuel

 

[TCluff]

well, i ran an overhead and found every rocker out at about 4-6 thousandths this lowered my ex temp at idle about 50 deg, picked up a little power in the bottom, but still have high ex temp with the tst only on 4x4, i can burry my pyro before 90mph at 1600 deg

Lift pump dying?

lowest fuel pressure hit 12psi with ramifier at full, tst on 7x7 pre filter, maybe i have a bad pyro
