Free horsepower?
I just bought my first diesel a 2000 f-350 crew cab lariat 4x4 and was wondering if there was anything that can be done to improve HP spending little or no money. Wife already thinks I spent too much money. Any advise would be appreciated thanks.

You can add a 10K ohm resistor across the ICP (Injection Control Pressure) sensors plug. This fools the computer into thinking the the injection pressure is low and makes it add a bit more fuel. It has the same effect as bumping up the timing on a gasser. Total cost is about $0.24 for the resistor and 10 minutes out of your day. It's worth about 15-20 HP and 30-40 torque on a stock truck.
You can also disconnect the wastegate. Do this by unplugging the small red pressure line on the drivers side of the turbo and capping the line. Cost is free, it takes 30 seconds and will add 5-10HP and 10-15lb.ft.
You can build your own intake system for less than $50. Do a search for "open air intake" or "Tymar".
A muffler shop can straight pipe you exhaust for around 50 bones.
Plenty of the mods in my sig were cheap or free. Shoot me an e-mail, I'll be glad to explain any of them to you.

Too much boost for what? On a otherwise stock truck you may get 20-22 psi. That won't add much (if any) power, but it will help to control EGT's, and it certainly won't damage anything.
You won't have to worry about overboosting the engine. Unless you wire the wastegate shut it will still force open on it's own, kind of a built in safety factor.

10 k mod
When connecting the resistor, is there a - or + side to the resistor when hooking it up. I have overheard someone talk about the resistor being hooked up backwards. Is this possible?
