Spending an ass-load of time on a map getting it "just right" is a waste of time, because the conditions the motor's being tuned under won't ever exist in exactly the same manner ever again. Temperatures change, parts wear, humidity is different, and on and on. The ECU can already adapt to those changes. The goal of the tuner is to make a map that's good enough to allow the ECU to work well in all conditions. If you really go after the details, at some point you're actually going to be fighting the learning features of the ECU.

Maybe you're right. I'm not a tuner, so I don't know. In fact nobody can possibley say with any certainty whether my car would be happier if I had gone to a dyno-tuner that would have spent 1/4 the time.
Personally I'm just glad Ed stood behind his work enough to come up here and make it right. The car seems very happy to me. The EGT's and boost are nice and low but it still feels like a rocket. I'm happy.
