At what size injector does that idle start getting choppy? I originally had 180/100's, then had them built to 300's and kept the 100% nozzle until I went T4 and built trans. My truck was just going to be a toy but it's turned into a daily driver, so I'm wanting to ditch that choppy idle but keep the power.. I would think the choppiness comes from nozzle size, but every 250cc and under with 100% nozzle I've seen idle smooth like stock. Does it sound like a UVCH problem, or is that just associated with 300cc and larger injectors? The injectors don't miss, haze, or anything. They run really smooth throughout the rpm's and fuel hard, just choppy at idle. Just trying to figure this out before I go through with trading someone for 238's or 250's in hopes of a smoother idle..
