you know I'm there too, while at the power level of my Fury I'm not really getting the 'economy' out of it, it's been a lot of fun to learn and gets thumbs up everywhere. Building #2 with a 5.7 and a single turbo in my Coronet!
To me, nitrous might be 'instant on' power at the track, but is not 'always available' like a turbo or supercharger.
