OK some more info, I took it for my commute today. 55 miles 1 way & it ran sooooo much better than before. Upto 5K RPM it is entirely a new bike, good grunt & off idle response is excellent.
Above 5K it is significantly better than before. If anything the delay has gone down from 2 seconds to may be .5 secs. Over all if you want a number, it is 85% better than before. I cant believe the previous guy tuned it so badly & didnt bother to change it back to stock.
Still waiting on the tank to get over so I can figure out my new MPG.
