what do you mean by bucking.....is it like kinda stalling....if so , that level 5 extreme is basically draining the fuel out of the rail....time to upgrade fuel system.

I would guess that it has something to do with your dpf. You better fill out your signature before people start to jump your @$$ for it.

try to move ur max egt to 1550 and then move ur max boost to 45psi..... u may have ur defueling settings set to low............... or a better way, push enter twice and a screen will pop up and then hit enter again. This will shut off ur saftey features for 1 minute.... then run it WOT and see if it bucks.............. if it doesnt buck its that ur max settings are to low

yea it defueling........... that is what backdown is....... so it defueled 37% so ur max settings on ur egt's and boost are too low

i just went out and warmed up the truck...i tried a full throttle run and checked the guages again. backdown was at 100%. i raised the egt setting to 1550 and the boost to 45 , i tried another run and now the truck is fine . backdown was only 5%, i guess this is normal..yhanks for all your help..this site is a awesome place for info...
