P72's were available in OBD1, OBD2a and OBD2b.
Maybe it is just me, but I don't see the harm in running both a chipped ECU and VAFC assuming the chipped ECU is actually tuned. The VAFC would come in handy to make small adjustments at the track when carrying around a laptop and all the required cables is a PITA.
