I just got my truck on the rollers this morning. The dyno was a Mustang dyno. I had the people at G&J Diesel simulate a large load to really work the turbo to its full potential. The setup I am running is the same as my signature. This run was with the larger exhaust housing. Roughly 260rwhp and 400ft lbs.

Yes, the last run I did was with a GM-3 running 18psi and made 203rwhp and 331ft lbs with my old 150K miles injectors. This run was with the larger ATT and 2300psi Bosch Injectors.
 
With a load, yes. It walks circles around the GM-3 when loaded. Unloaded, I don't feel much of a difference since it isn't loading it up.
 
What boost were you at for full load on the ATT?

My hats off to you for a dyno run!
 
I have the other smaller housing I am going to swap in on Friday hopefully. I think fuel right now is pretty well set but I will see how this smaller housing reacts. I think with a bit faster spooling housing I can bring torque up but all things considered it still built great torque even high in the RPM so I am not unhappy about that at all. Also I am going to buy a stage II snow performance water/meth kit from a friend of mine as soon as I get my tax return back, and when I can, I plan on going to the dyno with the smaller housing. I will make two runs without running the water meth and the final run running it with a 20% mix. This way not only will we be able to see the difference in housings, but will also be able to see the benefits of the water/meth injection, so it will be good info. Hope you guys stay tuned
 
I am glad to. I know a lot of people here have jobs and are super busy a lot and do not have the time or money to dyno, and since I am fairly bill free still and have minor income here and there, it is easier for me to dyno my pickup than some I think, and I am glad to do it. I know you guys like to see good dyno results. I try to be helpful when I can.
 
Not at all. I thought torque would have been a tad higher comparable to horsepower but for as much torque as I made that high in the RPM, I cannot complain. Maybe the smaller housing will bring it up a bit. Time will tell
