Hi all,
I contacted the previous owner of the Golf GTI, who advised that he had it remapped by Revo to 241bhp and 358Nm of torque... that explains why it goes like sh*t off a shovel!
I timed my 0-60 at 6.1 secs on the first run and 6.0 secs on the second and at Craig airfield, I accelerated from 0-100mph in 10.4 secs - these figures seem astonishing for a remapped bog standard GTI!
I'll put some pics up, because I also found out the Recaro bucket seats that are in my car are very rare and were a £1,500 optional extra when the car was new.
So on the basis of the above, I would strongly recommend Revo as an outfit to remap your car!
