turn up fuel and rpm on a 3208 Cat

If you really want to make a screamer, find some marine injectors, they got up to 475hp out of these.
Tools needed-7/16" socket, a short extension or 2, and a screwdriver. If you look on the top of the pump you'll see a cover with 2 bolts that's about the same size as a Holley carb's float bowl. Fuel does come out sometimes, and does not need bleeding afterwards. Under it is a screw with a jamb nut. If you hit the accel. linkage you'll see a little pin come up. The screw stops the pin and thus, limits fuel. So adjust it as far up as you can as long as you can tolerate the black smoke. Most turbo'd 3208's can run fine with the screw all the way out(removed). And just behind that is the high rpm governor adjustment. It's labeled as 'high idle', but only go 2-3 turns at a time as to keep it under 3200 no load. Backing the screw out raises the rpm. One more adjustment is the pre-boost power. This is up in the front of the other 2 adjustments. It's round & has 3 bolts holding it & 6 holes in it. Take all 3 bolts out and you may have to smack it with something to break it loose(mosly from paint). Now tighten it like you're screwing it in tighter, that makes the power come in sooner. If you go 'til it stops, then you may see lots of smoke if you mash down on the pedal. Back it out as needed.
