Dyno results
Well that was entertaining. I learned more than I bargained for.
Truck ran fine. Almost. Turns out, I forgot *cough* to include an important detail on my DP tuner form, that being I have stealth pumps.
So I learned that he needs to know that to have the programming correct.
Ok, I knew that, I just biffed.
Or you might let off the throttle and just konk out. Oops. That's already getting handled (insert brownie points for Jodys customer service here, even though it was MY mistake.)
Nevertheless, at the rear wheels, 326 and 665 on the 80 econo setting, even with a glitch in the program.
The guy operating the dyno said take either of them / .7 to approximate flywheel. If that's accurate, then those are more like 465/950 . . . which makes me say, no flippin way. That can't be right, can it?

id say hes close, going by your driveline loss , you might be making over 400hp i always did 30% for a driveline loss
so those are good numbers,
do you have injectors done or stock ones?
and would you mint sharing what you paid for stelth pump?

Driveline loss for our trucks is more like 18% loss.
Super duties usually dyno about 210-215 stock, that's 40/250 hp or 16%
Your flywheel numbers are more like 380-385 max.
But that doesn't matter anyway, does it.
What gets to the ground is what matters, therefore you make 326hp.
Are you saying this was WITHOUT tunes for Big Oil? Are you gonna dyno again after the oil?

See if I can answer all of these at once.
He was using 30%. I didnt know if that was accurate. I think I'm more inclined to believe the 18%.
Yes, stock injectors still.
Yes, without the big oil programming. It hadn't reared its head in just driving around but it was pretty obvious something was hokey on the drum. And I think I might go back after that gets addressed.
GREGROB pretty much nailed it though. What matters is on the ground, and like I said yesterday, I just wanted a number, any number, I didn't care. Now I have a number.
It does tell me how to drive. I dont have any great de$ire right now to be doing rods.
Edit: oh yeah, the stealth. I want to say it was $2500. But check with Bean, I really don't remember exactly. At the time, injectors were hot on the list. Now . . . standby. I think I'm content without them.

Well it isnt animosity at all. Believe me, I think about modded injectors and get the quivers. The issue is doing that isn't just doing injectors, and I see by your post your head is already those two steps ahead of the game. That was a little of the incentive for the dyno, to see just where the heck its at. You know probably better than I, adding more horsies with injectors is going to be rods for starters, and might as well be a full package deal with heads, studs, etc.
I don't think thats tenable at the moment.
I like the word animosity though. You go ahead and scintillate me with your ostentatious vernacular all day long. :-)
