Let me add this tid bit.

This is pretty much gospel as far as I am concerned.
"IF" you are going to runa 6.5 TD with some major power improvements you need a good set of gauges on the beast.

WATER TEMP, EGT, BOOST

you have got to drive these little monsters on the gauges and there is really no exception especially when your asking them to work hard.

The Coolant temp, EGT can all get hinky depending on the outside conditions (TEMP, Altitude and the load)

This is not a plant your boot and forget it engine, you have to be on top of things.

Just my opinion
