haha this guy

tranny upgrade, lift pump, and custom EFI live tuning to start with. that should get you close to 600HP and in the 12s in the quarter.

after that its all guessing for me, but I'm going to say either a twin setup using the factory turbo a single like turbo like a cheetah, upgraded/dual CP3's, and injectors

it all depends on what your looking to do with the truck, what are your goals?

I stay away from anything ATS

Airdog 2 or Fass, whatever you like the best

Just the reputation that ATS have given themselves, really just rubs me the wrong way

for a high 12 second truck you could get away with

-built trans
-ppe hot +2 or EFI live
-Lift pump
-intake
-Exhaust
-front end upgrades

Add compound turbo chargers(using the stock turbo), twin CP3's and you could get low 12's

to get into the 11's you're gona need new pistons, rods, head studs, injectors, and maybe a bigger set of turbos, and your trans will have to be built to the nuts

as far as the rail pressure code you can get the fuel rail shim kit to allow the rail to hold pressure longer

and head studs are only worth it if you plan on making lots of boost(more than the stock turbo is capable of)
