is this true hp or just numbers
 

I have an 06 3/4 ton 6 speed standard my mods are banks air ram w/ scoop and banks automind which is supposed to add 100 hp and the air ram adds about 25 hp so does that put me at 450 hp or is it just numbers?

Just numbers! Other things go into the equation like fuel pressure! Banks is pretty good at not over stating their products. A dyno would give the right answer but somewhere near 400 is possible!

So how much hp can you get with stock injecters or should i just start with exhaust, air flow , like intake and intercooler?

I've seen 500hp+ with stock injectors

What all mods was done?

Intake, exhaust, CP3, Programmer! If you have the factory 4" exhaust leave it alone plenty of flow!

remember you do not start with 325hp at the wheels, it is 325hp at the crank, once you consider dirvetrain losses you are about 15-20% lower

So the cp3 makes a big difference I'm new to diesels
