It all depends what speed you are running with these lly's on the dyno. I started my run at 70mph and pulled to 120mph Mine made 407HP, 767TRQ. I didn't get a stock pull bc we were pressed for time, You need to do a mouth peice and intake if you don't have one. I noticed the biggest gain with that mod, I also get aroud 20mpg with the mods in my sig. hope this helps!

to dyno, you let it shift into 4th, hold it, then floor it. why start out at 70mph??? you didnt go 120mph in 4th gear thats for sure...

Thanks man, those were the numbers i was expecting, i'l keep that in mind for the next time i run it, but the mouthpiece is on the way and intake as soon as i have time to look for one and order it, what would you reccomend for an intake?

OD dynoing is not a fair way to dyno,4th gear and most go from 45MPH thruout 100MPH if it holds the gear that long! IIRC,thats how it is..i had dynoed a few of our trucks and thats how all of them did it and my last dyno run read 420HP/1100TQR and they say the Cummins has more TQR

..

420/1100??? either the dyno wasnt loading or opperator error. Ive never seen that much tq for that amount of HP, even on a cummins..

That does seem really high, when i dynoed my truck my buddy was there with his cummins and his horsepower was just about even with mine but his torque was sky high compared to mine. He had the same mods as i, plus intake manifold.
