They are the same just slightly different tunes on them because of different o2 sensor locations and possibly less obd compatibility on the v7

so far from what i can state is that the V7 ecu holds about 1.4bar of boost.
V8 for some reason when w.o.t, fail safe comes on and boost stays at .6bar.
dont know what is going on.

but thanks guys.
