cpr rottweiler and power commander

Hello I've had my 2010 SD since may and I love it,I'm thinking of fitting a CPR rottweiler air intake with a power commander V I would appreciate any views on this just to see if its worthwhile spending the extra money ? Thank you.

Thank you very much what's the tuneecu ? I hadn't heard of this I know the pcv is a bit more plus the dyno but I don't mind so much if its going to really improve the bike I really appreciate your advice
