I was concerned about the low cold idle (1000 rpm) so today I yanked the pipe cap out (was surprised...but maybe it shouldn't surprise...it got sucked to the other end of the tube near the EGR valve) and drilled the hole out from 3/16 to 15/64ths.
Perfect. Now the semi-cold idle is up at 1250 rpm (good compromise), and the revs drop properly still. Maybe they drop a tad slower, but I don't care. Maybe I'm making this up, but I also think throttle-tip in is a bit more responsive.
I'll see what the cold idle is for real tomorrow morning. Happy as heck. Great mod, and essentially free too.
