Everyone, thanks for all the good info, Weather was too bad to get it to the Dyno.( 2 1/2 hour ride) After a little run this weekend, the speedo doesn't lie (I hope). The Busa's weight just makes it seem slower. Don't have the money for TI exhaust, got a full D&D because of the price. Also 16 front sprocket. Both these get put in this Friday, hope there is a little difference. looking for a PC. The only one listed is the PC11, is this the only one that will work with a 2001? Does the TRE really make a difference? I see some mixed feelings on that subject. I would like to go all out and get cams but I like having a warranty just incase something does happen.
