so, who has installed DD3's on an H.O. and dynoed? what increase did you see? what were your numbers? no boxes/reprogrammers please, just stock truck with the injectors...

the reason i ask...i just purchased a set and am hopefully going to the dyno this weekend to see where i am at with horsepower, i just want an idea of what i should see. i also understand weather conditions add considerable fluctuations.

 

You will need some type of boost fooler or boost clip to run a stage 3 and no box. Otherwise the high boost level will set an overboost code.

 

my Comp box will take care of that...

I sent you a PM concerning this, let me know what you think...

Thanks, Pat

 

I've installed lots of DD3's in HO trucks, and everyone I watched dyno did between 340 to 350 hp on just the injectors alone.
