Messing with injector pump
I here you guys talking about turning the pumps up and down all the time. My truck barely smokes at all. Is it going to make a noticeable difference in power if I turn in up. Also I live in a city where each rig has to pass emission tests. Currently my truck will pass the tests fine, if I turn the pump up will it effect the results???

half a flat
yes you could turn it up, it will increase your fuel output, but to much and you'll get lots of black smoke, half a flat is from the flat side on the allen wrench to the the corner of the allen, this is all i would go a little bit goes along ways

I just turned mine up and I went about 90 degrees I dont know that helps because I got headers and my pyro is acting pretty normal unloaded. She is cranking alot more power at the high rpms but I think sombody may have turned it down. I don't know but I think one flat is about a 60 degree turn. so I must ethier have alot of air or that pump was turned down to much

10 secounds I drove her for about 20 miles before I did it. rough idle for about a minute. It stinks having your hand down there trying to find the allen screw and then turning it clock wise especially with the motor being hot and the smell of diesel and a few beers that I had while I was doing the work didn't help matters.Its done and it runs like a champ thats all I care about. my hand and wrist were falling asleep I wish I had smaller hands at times.

Please enlighten us to where this adjustment is made. I can't get any smoke unless I am power braking, so I think I have room to turn it up a tad. Might help my "low power" situation.
Thanks
