turning in the fuel screw...

[Don Tanklage]

with the afc at wfo all the time my truck seems to make less power as i turn in the fuel screw



it smokes more



sounds different



but i think it is slowing down...



i do not have a dyno at this shop so i am going by seat of the pants



is this because i am already past the h1c's limits?

smokes more when? cruising or full power accelerating? my truck would smoke like a train with the h1c, newer turbo cleared it up and made a little more power.

it doesnt smoke at all cruising or idling, when i punch it it can fill the street curb to curb, then it tries to clean up



it was able to clean up better after green leafing the afc and with the fuel screw way out. as soon as i got to 2 turns in tho, it does not clean up as well and feels slower



more smoke does not always mean more power, does it?

... . more smoke does not always mean more power, does it?

No. In fact, in a modern diesel, it almost always points to a fuelling or airflow problem.

no, a decent haze will usually light a turbo quicker than a clean exhaust, but if you're rolling a black tire fire out the pipe, you should probably tighten up the AFC... it'll probably light quicker

thank you



yes, that makes sense, and i will have to hook it back up to tow, thats for sure...



i really meant once it was lit though
