made 402 rwhp on a mustang dynojet. no tq numbers this week because their optical sensor wasnt picking up the rpm. should make easily 800 rwtq. http://www.ls1tech.com/forums/images/smilies/LS1Tech/gr_chug.gif What do you all think? Is this about right for the programer? what have others made?

truck is a 2003 2500HD Duramax/Allison combo COMPLETELY STOCK other than the Edge Hot Juice w/ Attitude monitor. not even a muffler or air filter. http://www.ls1tech.com/forums/images/smilies/LS1Tech/gr_hail.gif Duramax diesel.
the dyno operator i dont think knew much about 5 speed autos in diesels and had a hard time keeping it from shifting down to 3rd gear. they let the truck shift itself into 4th. each pull took about 30 seconds to get it into 4th gear to get ready to do a pull. this resulted in HOT HOT turbo. so i think the truck has more left in it. http://www.ls1tech.com/forums/images/smilies/LS1Tech/gr_eek2.gif It took the operator 2-3 WOT runs to get the truck to pull in 4th gear alone.
the drivetrain loss has to be enormous on this beast. with the 14 bolt 12.5" rear, 5 speed auto, and 2 piece driveshaft - not to mention heavy steal truck wheels and heavy load tires. lol. i think 20% is easily lost - maybe more.
Here is the dynochart, not pretty since it shows hardly any rpm (not that diesels have a long rpm band). dynoed in 85 degree florida heat (in march) http://www.ls1tech.com/forums/images/smilies/LS1Tech/gr_judge.gif hopefully will have a better looking run next time.
