ok so i was woundering? i have a 6.9 idi diesel and i was trying to figure out is there any way i can tune up the horse power with out messing with the injector pump...??? i thought about dropping the motor and bore it and all that goodies but i dont know if i can do that on a diesel motor and i would rather do all the little things first? and suggetions???

 

if motor has good compression and overall good running order then id do all the air and fuel mods. personally i think DPS stuff is good but alot of people disagree. im going to get alot of DPS stuff soon. so turbo (holset hx35) and DPS injectors and injection pump.
