Just bought a gti with 21,000 miles on the clock, my friend has a mk5 R32, i reciently had my car remapped from a company down south, i ran it in with the new remap for about 200miles, all the time it was getting faster as the ecu was learning the new software,
i then met my friend in his R32 at the traffic lights and it left him for dust, this is not due to my friends driving or shifting as he is a good driver.
i was wondering if my car has had other mods in it that i dont know about

from the previous owner, also i bought it from a dealer and it was not private.
i may just take it to a rolling road.
any feedback would be good, cheers
