Chris,
Thanks for posting your 3rd gear numbers. It helps clear up what I have been trying find elsewhere. We see a jump in the torque numbers (10-15%) between dynoing in OD vs Direct (4th gear vs 3rd gear in your truck). The horsepower numbers are not affected nearly as much. That coincides with what I have been reading.

On average we can expect our trucks to show around 10% higher torque numbers if we dyno in overdrive. Horsepower numbers are likely only 5%-8% higher on average when dynoing in overdrive.

I expect my torque numbers in 4th gear would be around 1050-1080ft/lbs. My fuel tunes run very low timing to keep the motor from eating the rods/pistons (injection timing is what makes torque).

When I go back to BTS I will do both 4th & 5th gear dyno pulls to help validate this again.

what happend to the injectors for the longest traveled to the dyno...

Curtis i have no idea what your talking about. Oh and the 6.0 came a lot farther .

John its no problem. Take a look at my pm and lmk what you think.

let me know when you ga back john, ill drive the long distance and see what ya do the next time, o and the injecters went to busta, they were going to come but decided they couldnt so they got shipped.

hey ed what numbers did you put down

321 and 745 with just injecters and 377 and 871 with a hypertech on it.

i thought you put down a little more than that i guess thats what i get for thinking

Ok guys not sure if you heard but the OKC trip is a no go. KC got called out!

Does anyone on here know a diesel tech or someone who works for a Chevy dealer?

I need to find a flexplate holder (Kent Moore PN J-44643) to hold the flexplate in place for proper torque. On my small block/big block chevy builds it wasn't a big deal (those only needed to be torqued to 85ft/lbs) and the factory flexplates had holes machined in where you could easily hold it with a pry bar or 1/2" extension. Not the same deal on a diesel with a solid aftermarket flexplate (this one torques in three steps starting at 60ft/lbs and needs to go to at least 200ft/lbs).

WOW!!!!!!!!!!!!!!!!!!!!!
