if stock P13 if getting chipped or hondata,chrome ETC. P72 all the way because theres little to no aftermarket support for the P13. the P72 has all the proper functions such as I.A.B ,knock sensor that the P28 lacks the P30 has knock sensor but lacks I.A.B of course thats the orginal state and can be added to them if the someone knew what they are doing.
