i was wondering if anyone has advanced a db2 injection pump and how far to advance it from the marks on the block and the pump and if i could either get some pics or detailed instructions how to do it that would be great and will i be able to feel the difference.

Here is a good website that explains how to do it nicely;

I highly advise you to put at a minimum a EGT and boost gage on before you start turning the pump up on a 6.5TD. Even if you are very carefull on these motors they can still be pushed over their limit easily.
Most people on here only turn it up a 1/4 turn, do a search and do some research in the stickies.
Hope this helps!

by advance what do you mean? the marks on the block and pump are for timing purposes only. i'd leave those alone unless the engine is out of time. if you want to "turn up" the pump 1/4 turn is the most i'd do(but my truck is electronic so i can't even do that). get boost and EGT gauges before messing with the pump at all. more fuel means you'll have to add more boost as well to keep the EGTs down.

More fuel means you'll have to add more boost as well to keep the EGTs down.

Not to mention to use that extra fuel. Dumping in more fuel without more air is a waste of fuel, and will result in black smoke and poor milage. An engine needs two things to run, fuel and air. You are limited by the one you have least of.

More fuel without more boost will result in stock power with high EGT's, black smoke, and poor fuel milage.

More boost without more fuel will result in a small increase in power over stock to a point, and beyond that, you're just adding air without fuel, and getting excessive IAT's.

Now, I say that boost will increase power a little because when I'm going WOT up a hill near me, there is a haze of smoke out the exhaust. More boost (air) will put in air to burn the fuel that is coming out as smoke, and turn that black smoke into power. Not a lot, but it will increase a little.

Now, to get appricable gains, you're going to need to add both air and fuel. That is because fuel cannot burn alone, and air cannot burn alone, but together, they do, and the more of them you have together, the more "boom" there is.

well ... when you advance the pump timing you put fuel in the hole faster and longer. end results are, 1. real power boost. 2. (this is the bad one ) you will burn holes in the tops of the pistons . so if you want power turn it all the way. if you want to keep your motor to gather and keep it some what dependable dont change it

Advance by ear. If it rattles on acceleration you've went to far. Don't move pump while engine is running. Turning the fuel up advances the timing just a little by design. So turn fuel up first and then play with timing. Turn pump 1/16th of an inch towards the drivers side would be a good start.

If it starts running to good, expect engine failure in the near future.

X2. Did many 6.2s that way. Tried and true method. I would have said marbly sound but yep.

If you turn it up expect your cold weather starting to be a little harder, my truck used to hate me below 20* fahrenheit if i didnt plug the block heater in when i had my timing and fuel cranked. I turned her down some this year for the winter and had much better luck.

I turned my pump up til the screw stopped, got a little better fuel mileage (from adding MUCH more boost) and have also noticed poor cold weather starting in the winter time (especially in MN). Usually anything below 15 deg ole cheyenne doesn't start up. But I dont drive it much in college, so starting it up every 2-3 weeks during the winter time doesn't help either.

As far as EGT's go, I dont get above 1000 deg.
