What is the best set-up to gain the most HP? I have a 2005 2500 CTD 4x4 3:73. I do not necessarily want the truck to sound louder, though. Would it be fuel inj., chip, module, twin turbo, exhaust, air intake, tranny? What is the BEST set-up?

 

Gauges first, then FASS or Air Dog pusher pump and then all the abv. If you still need more go to drugs.

 

Yes Guages first, then
1. intake and exhaust
2. Performance module or programmer
3.fuel system/ pusher pump
4. Turbo setup single or twins pending on what goals are O ring head may be neccessary
5. Injectors
6. water/methanol injection and or Nitrous O-ring definitely neccesary.
You will also need a new clutch if you have a manual or a built transmission and Billet Torque convertor if you have a auto. Fill in your signature with truck description so everyone knows exactly what you are working with

 

I agree with Kyle. Gauges 1st, Intake + exhaust 2nd, Then I would go transmission next. No matter how much power your make at the flywheel if it does not make it to the ground what is the use. To many of us are going to destroy the tranny at the ease of making big power with the performance boxes. I almost did the same with my allison in my dmax with the hot juice. I plan on upgrading this tranny asap.

 

Get a pyro and a box and keep your foot out of it first. Then get exhaust. Then get an airbox. Then blow the turbo and get a new one it's time for a bigger box, and a clutch/tranny upgrade.

IMHO you do NOT need to waste hundreds of $ if all you ever plan on doing is running something tame like an EZ. Get gauges and the EZ and see what happens. Intakes and exhaust (for performance reasons) are way oversold.

My my 2 centavos, YMMV, IMHO, FWIW,

Buy the Power Pup with outlook monitor before you buy an EZ - the pup blows the doors off an EZ. This will take care of gauges & give you very good smooth power choices. The tst also works well - but more aggressive power.
Good luck.

 

Whenever you add fuel you need to compensate with freeing up exhaust and helping the turbo breathe so do intake and exhaust before you add fuel it only makes sense. A restricting muffler won't let exhaust escape from turbo which will cause excessive EGT's. Stock Airbox flows 300cfm aftermarket intake will flow at least 700cfm. Always increase efficiency before you start adding fuel on any engine

 

Strap on a TST box with the gauges built in. The best bang for the buck by far when one wants the Maximum HP per dollar spent.

It whips all the boxes in raw HP and TQ.

Its adjustable and if you keep the power levels turned down...everything will be ok.

Keep your boost under 38 PSI to save your 05 intercooler from popping.

The stock air box certianly flows more air than 300 CFM if you are measuring it in a true comparison manner. If it only flowed 300 CFM the stock engine would not be able to produce any boost.

Remember the engine will use at least 300 CFM even it is is normally aspirated at 3000 RPM. Adding a turbo will easily double that at 28 PSI.

An aftermarket air intake system is a good idea in the end though.
