7.3 tow tune dyno

Just out of curiosity has anyone dyno'd their towing tunes? I'm interested to see if we can find some graphs and see how they stack up against the new trucks. I do understand we're dealing with old school tech on the 7.3 I'm specifically talking towing tunes not all out. Thanks in advance!

I am sure through the ages there has been graphs posted but you need to be more specific. Stock injectors or bigger injectors or turbo or hpop. There is no comparison to a stock injected maxed out tune 7.3 to a bone stock 6.7 as they put down 360ish hp and a stock injected maxed out 7.3 is still 30+ hp shy of that. Now you can make a 7.3 tow very well and be comparable to a 6.7... my dually 7.3 and my 6.7 run identical numbers and tow the same. I got better mpg with my dually while towing but i get better mpg with my 6.7 empty by like 5mpg on the highway.

385/866 on the tow tune in 2010. No smoke, max egt of 1100.

I was looking for graphs for bigger injector 7.3 trucks. I kinda meant this to be vague. I've done searches with not much success. Seems like most if not all of the graphs posted are all out tunes. I'm just super curious to see a graph from a stage 2 injectored 7.3 vs a stock 6.4 or 6.7.

Uncool what was your setup on that dyno pass?

300/200's, S476, gen3, studs, springs, pulled to 3600 RPM.

385hp with stock mechanical fuel pump (OBS) with 160 split shot stageIIs and 17* hpop. Add another 10hp with electric fuel pump., all with real old tow tunes. Add more hp with big Hpop. I installed twin hpops, never dyno'ed with them but SOTP was perceptable. All with 1.0 OBS stock turbo.
