GTX MATT, Yeah I get it, good points, and I agree. Also, would love to get myself set up with wide band tuning ability and maybe will if / when I get the time. Right now I need to keep it simple and drivable so I can use it and enjoy it. Long term plan is either put the full 440 drivetrain from radiator back out of a D150 I have, or go 3rd gen hemi. But nether of those are likely to happen for several years yet. And so far, the 318 seems to be solid, so I may just leave it as is.
