Break 500HP and 1000ftlbs

What do you need to break these numbers? Other than money... I have and 03 with a 6 speed
Air intake
intake manifold
4' exhaust
ARP studs
SCT custom tunes
Fuel pressure spring upgrade
EGR delete
bullet proof oil cooler
ccv
zoodad

Can I break those numbers with bigger injectors and custom tuning? I'd like to keep stock turbo if possible

Well upgrade your fuel system bigger injectors and you might touch 500hp with some good custom tuning. But it's tough to say without upgrading the turbo it's a close call I believe.

Well as of just yesterday, 485rwhp and 970ft-lbs of torque have been made with a MTW Stage 2 turbo and tuning. I think there is an exhaust in there as well.

Easier and cheaper to change the turbo.

And that kind of power can be used all the time provided that the timing isnt too far advanced I guess. I know I would be happy with 485/970 with just a turbo and tuning.

Now lets remember the stock Hp/torque ratings are 325/570. So how in the Heck does a Turbo/Tuning/Exhaust give you 160 more Hp and 400 more ft lbs of torque? Are you guys running the Looney tune to get these numbers?
Start Explaining !

Actually a stock truck will typically dyno at 270 hp and like 490 ft-lbs of torque, all at the rear wheels.

The simple truth is that diesels LOVE air more than they love diesel. Everyone thinks you have throw more diesel to get horse power but what is NOS?? NOS is nitrogen and oxygen. Nitrogen is inert (therefore does not burn or make power) and Oxygen is what causes the boom (so to speak) with diesel and guys can easily spray to over 500hp with stock injectors and all they are doing is adding in A LOT more Oxygen. Well a turbo can do something similar with more air. And what makes up air?? Nitrogen (~79%), Oxygen (~20%), and Argon (~1%). Well Nitrogen and Argon are inert (therefore dont burn and make power) and like NOS, compressing more air will put in more Oxygen and cause a cleaner burn, which means more CO2 is produced as opposed to CO (black smoke), therefore creating MORE POWER

Ok well that is text book answer. What no kidding is going down to make this happen is the Stage 2 simply flows A LOT more air than the stock turbo AND with a high performance tune (like the Looney or SPD or Xtreme X or ) AND PHP's Hercules FICM tune, you get just about every drop of fuel you can out of the injectors and into the cylinders, which is A LOT more fuel than is being delivered with stock ECM and FICM strategies; and BAM the motor starts making HIGH horse power numbers compared to stock.

So in summary you shoot in a sh!t load of air with ALL of the fuel that the stock injectors will flow and there you have it, a ~490rwhp ~970ft-lbs truck. Hope this helps explain it a little better for ya.

Plus it seems the MTW's don't run out of air at 3300 or so rpms either. These engines love to rev. Wasn't a few months ago, most were thinking around mid 400's was it for stock injectors.

Yes. From all the results that I have seen so far with these turbos. It really seems like the Stage 2 is the way to go if one is looking for an upgraded turbo with either stock or 155/50s or 175/stock injectors. The stage 1 is good for a stock replacement as it will out perform it in every way but if I were looking to spend money on making all the power I could with stock injectors or 155s, I would get the stage 2. JMO.
