Default Cheap Mods On A Stock Truck Thread.

post 'em boys. p/n's and links if you got 'em.

cheap mods on a stock truck-

1-remove the aneroid fuel control housing (AFC) (you will need a chisel or left handed drill bit to remove the break off screw) this device controls pre-boost fuel. this is done under 10psi of boost.

2-slide the fuel plate forward then back it up 1/16th to 1/8th of an inch. (you can play with this until your butt dyno says you got it where it wants it)

3-reinstall AFC and slide it all the way forward. (this is also butt-dyno adjustable. i got my best results with it all the way forward)

4-remove the 8mm plug on the top of the AFC. you'll see a starwheel. cranking this towards the engine makes it go forward. forward = more pre-boost fuel = more smoke.

5- go to NAPA. buy this filter: p/n FIL2790. this is known as a BHAF. remove the stock airbox and put this in it's place. bend up some sheet metal as a heat shield.

well there's a start. i'm a crappy teacher tho. !

you could also do some wastegate adjusting.

either buy the boost elbow........ or if you wanna go the cheap way, get a small 1/4in. hose clamp and clamp off the hose going from the back of the afc housing to the turbo. This will in result., increase the boost pressure that the turbo will push.

i took the washer with me to the hardware store. the washers are the same size. the new one is thinner than the stock one. the one i purchased does not have a lip on it like the stock one does.
