performance need advice
Looking at getting some minor performance and longevity for now. was going to order air dog from here should I get 150 or 100 not much performance probably ever 40 horse injectors and a little power from programmer eventually but ya. Does it come with a new pick up tube mine is broke about half way I think. Also going with 4 or 5 inch straight pipe will 5 inch hurt me? And the boost elbow. Don't know much about it but it should help some. And going with the K&N BHAF E-1796 Just the basics for now till I can afford a full set of gauges then I'll turn it up more. Thanks for the advice. This is mainly a work rig for hauling family, race car, tractors, hay etc.

FASS or AirDog 150GPH both comes with a standard DSII style draw tube. If you have an intank pump, you can get a DrawStraw V and for the standard module use the DrawStraw I. This is if you want to upgrade from the basic universal kit.
Obviously, a fuel system is important. Make sure you get some kind of gauges or built in gauges in a box.
5" exhaust will not hurt you in any way. Once it's out of the turbo, it's just going to the rear of the truck. It's job is then done. There are no scavenging affects like in a gasser.
I would recommend a standard BHAF and an outerwears. No cleaning to deal with and cheap. There are also some nice high flowing dry filters as well.

The factory ECM cuts the fueling curve if you exceed 22 or so psi at the manifold.
You have to "lie" to the computer to tell it that it is never seeing above say 20 psi. This way the ECM does not pull the fueling back.
The turbo has an actuator that works off a boost signal. At around 20psi, the gate begins to crank and limits boost by allowing some of the exhaust(drive energy) to go around the turbine and controls the speed of the turbo and hence boost.
We lie to the actuator with an adjustable or fixed bleed boost elbow or we clamp it off altogether.
None of this matters if you do not have more fuel than stock. So, a box, injectors, programmer or a combination.
More boost at stock fueling equals more heat for the inlet charge and less power.
