Interesting #'s. Nice work on Dyno getting the stock baseline. The HP #'s don't surprise me, but the torque #'s do. What kind of dyno, how'ed you load your truck for the run.

D-max's have a hard time getting boost up because tranny wants to downshift into fourth below about 2200 RPMs. When I did my dyno run of 532HP/950torque, I could only build 25pounds of boost. My truck makes 40 pounds on the street. My Torque #'s were low because of lack of boost.

Thanks for the info,
Rob
