Buying remapped cars
To be honest, this is a pretty general question that could relate to any car, but seeing as I'm looking at GTs, I may as well post it in here, especially given that when browsing other threads in here, it's clear that remapping the JTDMs is reasonably popular.
It's very rare to find ads for cars which mention being re-mapped. I'm not sure if this is because people worry it will put buyers off, or if there just genuinely aren't many out there. What options do you have for finding out a car's actual power and working out if it's been remapped? I'm guessing not many prior to purchase, and it would have to be a case of either getting a remapping expert to plug in and check the ecu, or possibly sticking it on a test bed?
