just to throw this out there:
1) ybbiz is 100% correct, go out for a ride in a dinan2 and see how you like it. Ive been for a cruise in one and it was pretty good, but definitely not the brute force that you feel with the piggies even on stage 1 for v3 (havent been in a jb3..but i assume similarish for the equivalent map)
2) there have been a few posts in this thread about adding a jb+ to the dinan. there is no worse thing you could do for your car than stack tunes. One tune manages a lot of variables based on inputs, when you mess with those variables you start getting output that is not what the tune was programmed for. To me thats nothing but dangerous, and if you were buying the dinan because you were concerned about warranty...adding a JB+ is essentially throwing that warranty in the toilet for a lot of money...might as well start with a piggyback.
