Oh, and I happened to speak to my SA after the pump and injector replacements and told him I thought I might have noticed some increase in turbo lag and decrease in acceleration, and his response was that he is surprised, because it was his understanding that the HPFP failures were thought to be related to breakdown of plastics within the fuel pump secondary to ethanol, and failure related to that effect; and that the new pumps were more resistant to ethanol effects. So he didn't think that there would be a 'detuning' as part of the recall.

Makes me wish I had dyno-ed the car before the recall so I could compare to the 'after'...

I had the car out again later today, and I still think there could be some greater lag, but I'm not convinced there's a drop in acceleration... that still feels GOOD!!
