No, I think I'm fine throughout most of the range at this point, maybe even a touch rich. I had a revelation while sleeping last night. After getting the new tach readings it seems like my readings are off by the perfect amount if I'm set for a v8. 2500=3200, 3500=4500. I triple checked it, gonna quadruple check it. Also explains why I couldn't appreciate it at lower rpms.

All from last weekend, a bit chilly today. So it looks like this was the problem. My tach adjustment is weird, and I needed to put the screw between 2 settings. It's now reading consistently 150 rpm high, which I can live with. Also checked my fuel consumption, which was 3.8+ mpg over 85 miles at 30-35 mph with a few short wot runs. About comparable to the 3.7 (maybe better, since I was averaging higher speed). I think I'm going to winterize tomorrow, so we'll pick this back up in the spring.
