Another factor in a build is what “mods” to the engine and what weight are you pulling? ....and where you doing this at? By most accounts I’m pretty “light” at 17800lb combined, but as Dave can account for, lots of interesting grades and temperatures out here in the west.
I live at 2,000 ft. and every road out of here takes you every degree of the compass while you're generally following your heading. The only thing I can attest to is that a non-HO 2004 CTD with a TST Powermax set on 5 will flame the stock converter on lockup and bite the input shaft off!
Billet input ATS to the purple people eating rescue, throw in a billet Banks converter and bounce off the egt limiter all day long at 40lbs. of boost!
