The Fass and Modied CP3 will help you out in the fuel delivery part, but now you will probably find the EGTs out of control and the transmission will be very upset with you. The Bully Dog shift kit is nothing more than a rebadged Trans Go Jr kit. To install the Full trans go kit you have to tear the complete transmission down. You have to change out the piston return springs on the C1 clutch pack, and there are several valves and springs that need to be changed in the Converter housing. I would look at the Suncoast Stg IV first. Get the transmission set up to handle the power, then put the power to it.

On the EGT issue, I would like to see a BD Supermax Turbo and a BD Full bore exhaust manifold to get the air flowing and get all that fuel burnt.

You will probably also have to shim your rail.

See, that first shot of power is the cheap shot. The initial upgrade is always the easiest and cheapest. Now you have considerably more work to do before you can add any more fuel, but if done right, you should wind up in the 450-500hp range no problem.

i think Jason(DieselNut)coverd it very well..

i would look at adding the second fuel delivery line from the pump to the rail and doing bigger rail fittings along with the Fass but before doing the bigger CP3 you mite wanna do some EGT's lowering or else your pistons will be TOAST..
Water/Meth kit will help alot along with a turbo upgrade and a BD Manifold along with a bigger inercooler but building your tranny will be your next step.
