having owed a r32 mk4/mk5 and now golf gti i would say the results show that ur mate needs to learn how to drive!!! a standard golf is not quicker than r32 and would only win when there is driver error , (shfting to early,late,etc) hence ur mate.now a remapped golf should be able to hold its own due to power then being similar and the difference in weight between both cars.from ur remap expect about 230 -240 depending on whos rolling road u have it tested on.
