Here are a few think you guys might like to know:

Unlike gasoline engines diesel engines can be easily modded to produce additional power by simply increasing the boost pressure and the amount of fuel injected. the chip you install will increase the boost pressure with your existing turbocharger and increase the pulse width to the fuel injections. However, this leads to elevated exhaust gas temperatures (EGT). It's very important to keep an eye on your EGT since prolong exposure to high EGT can destroy your turbo.

Water injection: High cylinder temperatures lead to high NOx emissions - water injection helps cut down emissions by a huge amount.

Diesel engines use fuel as a means to carry away heat to prevent high EGTs. When your engine puts out black smoke - its usually because it is running rich. Diesel engines do not like to be revved up - and when accelerating you will notice smoke early on and the smoke will disappear as the turbo spools up and your AFR reaches its optimum point.

Again, keep an eye on your EGT (Exhaust gas temp) if you're modifying your turbo diesel!
