In a way the 4 acts like the 6 for normal cars, but the 4's main features help on the DI cars. With the DI system staying in the 45-65% IDC range, the load varies a bit with the HPFP, it's not exclusively IDC driven. So the main goal was to find a load relationship between the IDC and HPFP signals to get more fueling at the top of the injection range, and add the boost input to allow some tuning on that front(as was on the HFS-6). The 56 might benefit from the 4 on high HP (big turbo) applications, for most MINI stuff, including the 53, the HFS-3 is good.
On the other hand, if you are buying a new kit, going to the 4 doesn't hurt, the GB price should be pretty attractive.
For the guys that bought the 3 recently, there will be a upgrade to change the controller out to the 4 after the GB has ended.
