Dyno jet? I was told they were no good for our trucks???, I dyno'd 460 and 851 in NOv on a Dynojet I was very dissapointed, I have twin lift pumps, and everything seems to be right on. Another guy, same year truck with no LP and a PPE hot +2 puts down 470 and 925????? I am going to try a Mustang (load cell) dyno!

x2 2850 and 28 psi boost netted me
503 and 1080 the more boost netted lower hp and higher tq on my truck with stock charger.3000us and 28 psi netted me 530 and 1080

no two truck are the same.
even more so when compareing LB7 to LLY, LBZ, LMM
X2 pressure is my friend..
all in all its not a bad starting point... really
given the tune really hasnt been changed since i put the new engine in. given the fact that the piston and bowls, compression and cam(06 lbz which is debatable weather it is different between that and a LB7
), compression ratio have all been changed to one extent or anotherfinally got my mpg today as well 410 to 26 gallons weighing 9,200lb ( 2,000# of sand in the back)= 15.7 mpg with alot of idle time and winter grade fuel.. this include the dyno pulls as well

what pressure are you guys running i've never tried over 25000-26000 psi how high can you go safely ? current tune is around 3100 usec @ 25000 psi holds about 21k-22k rail pressure through the 1/4 .
DynoJet 248C, SuperFlow, Mustang same truck same tune all over 500rwhp
no two truck are the same.

Get you pressure up you will like what you see. I did 507 on Dynojet with winter fuel. Stingpuller, Fingers, Minisub where there. On LB7s I never really had to change the fueling to get the power. The timing is what varied. But what do I know. :cool2:
just now got your phone message better late than never haha shoot me your questions hear in pm or on myspace
the ol phone is going down hill in a fast way

I wouldnt worry about it, duramax's are wierd on the dyno.
With the stock original engine and BD turbo, my 7680lb truck trapped 107mph easy in the 1/4 mile. I think it dyno'd like 450-460 or something silly like that.

fasted track time is in the sig [email protected] wieghing 7200lb that was in bakersfield june 07
The ET calculator is close 465hp@7200 pounds. Still not bad for stock turbo and 2wd.
