I like the idea of the thread. I currently have the jb4 from Burger tuning.

The pros of the piggy back is the ability to switch maps on a fly. I can run stock map, map1 which is about 19-20psi and map 2 around 21-22psi. I personally love I can have more power than stock but not have to run 1 set psi at all times. I can use map 2 only for racing. Map 1 for daily driving. You can datalog and read codes. You can clear codes. No Cel with downpipes installed. I had the jb4 for 3 years on my m4 from 200 miles on the car to 22k with no issues. On the M6 I have the jb4 for about 3k miles so far.

The cons for me is that the limiter stays the same. I can't pass NY inspection without a flash tune. Install is a few hours and a bit of a pain in the a$$.
