Hello,

My friends got my old Octavia VRS and has a stage one tune on it from a reputable dealer here in the UK. I'm not saying it has got ECU safe on it but what would happen if I tried to read the file and it did have this one?

Would it just come up with an error in MPPS or would it screw the ECU up and would have to put only the original back on?

Just checking becasue i'd rather not lose him the remap thats on it.

Cheers,
Neil
