Started it for a second time and let it warm up to temp, checking balance etc and installing the stacks and filters. I waited until it came up to temp so that auto tune could do its thing (won't activate below operating temp), and as soon as it did I watched the ratio fatten up and the idle smoothed out... so cool. Drove it nicely at first letting it adjust the ratios some, then progressively got on it harder and it was just very happy. It's still learning, but I wasn't out to do a tune. The idle is the best the engine has ever had, maybe because the valves are all clean and the intake is well sealed and evenly fed. I snapped a couple quick pics as I don't normally get pics without the hood on. Later I will do a compression test to see how much it dropped (was 220+) with the thicker head gasket.
God I love this stupid car...
