Looking to get 500-600hp out of new truck

[Clmsnow]

I am in the process of buying and building a new truck. Looking at either an 06' or 07' 5. 9. I want to be in the 500-600hp range and have a few questions as I am unfamiliar with the Gen 3's. I think I am going with twins, DTT transmission, smarty, modified CP3 and either injectors or stacking a TST. Like I said, I am really unfamiliar with the new 5. 9 and all the goodies so my question is, does this seem like a good route to go to accomplish my goal? Is there better boxes to stack or injectors that work much better than others? Also, what kind of fuel mileage loss/gain should I expect to see and is there a cut off point(ie-500hp. vs 550hp. vs 600hp) where mileage and drivability really start to drop off or is there a point when the cost of making the power really rises? Obviosuly I will run all the gauges, exhaust, intake, and fuel mods I need to accomodate the power. Thanks in advance!

from what you have listed you look to be on the right path. look in my signature, just whats there gave me my 606hp i also have just a modified FCA. i drive mine everyday and get 20mpg or better depending on how i drive. happy bombing Oo.

500-600 range is rather easy in a common rail. look in my signature, only thing i could use is more turbo. stocker just isn't cutting it any more... ... ... ... ... ... LOL.

62-14, 90hp DDP injectors, programming. . That's all you need to be right at your top number. . This dynoed 543 uncorrected dynojet hp. That was before I updated my smarty. . It runs much better now. .

What are the pros/cons of twins?
