... Does power shifting really knock of a few 10ths?
Yes it does, but at what price?
I learned how to power shift Stangs when I raced them in the 80's-mid 90's. Became so second nature to me that I found it difficult NOT to power shift if I floored the accelerator pedal.
But even when executed perfectly, it will exact a toll on transmission synchros (and pretty much everything else in your drive train).
Personally, I don't think it's worth it ...
