Update:
As last night, everything seems normal on start and drive this morning.
It "seems" as if it may have more power, I'm pretty sure it pops up from that 2200-2800 rpm range a bit quicker than it used to. I'm shifting faster. As I said, it isn't a miracle cure, I'm not suddenly driving a muscle car or anything. It just feels a little more normal. I'll get it out on the highway this afternoon, and see what it's like in the 65-70 range.
The real difference is this: No more white smoke. There was a tiny bit right at start, as I was backing out, and driving 50 feet or so to the end of the driveway. But I really saw nothing at all as I went down the hill, and even in the regular spots where the position of the pedal/rpms/speed would usually produce a big puff. If I wanted to, I could usually really lay a smoke screen down the 1/2 mile hill out of the 'hood, but I just let it coast. This morning, I could not reproduce the smoke, even if I tried.
I'm going to drive it like this for a few days, top it off, and see what the MPG, make sure it isn't some fluke with the smoke, and get some high speed testing in. But so far, all seems good, and even to have turned out how I'd hoped it would.
Thanks!
