Are you sure you are playing with the torque screw?

Nope, that is the one alright.
You need to turn that screw OUT to get more fuel delivered at lower RPM's.

when I adjusted mine when it was non-turbocharged I noticed more smoke and backed it off. Now that it's turbocharged I have it adjusted out about half way and I only get smoke when I accelerate in overdrive uphill and my tranny wont downshift. I'll adjust it all the way out and mess with the main fuel screw once I get my gauges up.
I didn't see a performance increase with it when it was NA though.. I don't think the NA motors lack in fuel, just in air. So adding fuel isn't helping anything.

yeah. right now its a play toy/daily driver. once i get home and start towin again ime set it all back down to just above stock so nothin burns up lol. and yeah the idi n/a is definately the lack of air. plenty of fuel to shove just the air needs to be more plentiful. and im not slappin a turbo on it either. all the guys around have turbos and i just want mine original lol.
You ain't gonna see any difference without a turbo, might see a slight diff on a dyno. Why so advanced 12*, turboed set at 9.5* non 8.5* so I've heard.
No turbo, now I get it.
Person in the left lane at a stop light after tailgateing me: You know all that damn black smoke is polluting the enviornment!!!!!!!
ME: Got ya off my A$$ didnt it?

Nothing wrong with rolling a little coal on occasion, just don't go to crazy or the smoke ****'s will gitcha.
well,environment reasons aside,there's no point in sending out unburnt fuel (rolling coal) out the tail pipe with diesel reaching up close to $4 a gallon right now either lol.
if there was a way to turn down the fuel below seeing 0 smoke and loose 10hp but gain .5 MPG id be doing it right about now lol.
id be careful with that particular screw if that adjusts the low rpm fuel flow,because as we know,the easier we take off from a start (little and slowly ease into the skinny) to get the heavy truck moving,the better the fuel economy will be.
