1. Slightly quicker start up warm and cold.
2. Idle is about the same. Idle was smooth before the change so I'm not surprised.
3. BIG improvement in acceleration, felt and measured. I went to a known 1800 foot marked area with little traffic. Started from a stop and WOT to the end. With stock coils = 0.40 seconds slower.
4. I'll update with mileage differences in a few tank fulls.

its more new vs old thing, the coils add nothing much if any at all there have been a number of tests that showed without a doubt that "H.O/performance" coils showed zero gains.
