yes keep it to 1/4 turn or less. if you go farther it will run the risk of siezing up.

10-4. Its a buddys truck. He just put 4" exhaust on it and now he wants a little smoke. I told him those engines can only handle so much. We'll see how it goes.

i turned my fuel up on my 6.5 diesel 1993, the fuel screw was in the fuel res. in the injector pump. (10 min mod)i know about runnaways so i found out how to cut off the fuel on mine ( green or red wire ontop of injector pump)under the hood if i ever start her up and she opens up on me. acurate temp readingsis a must

You have a Ds4 pump which is electronically controlled. The only way I know to turn them up is to buy a ecm that is turned up.
