Think hes going off an earlier thread whereby the bloke thought he was getting a sedox performance remap ( European company - never heard of them), but instead he used a remap that he wrote himself instead (which I guess is a PDTuning remap).
Either way, I think there is a big difference with selling someone a Revo remap and a PDTuning remap. A Sedox/Pdtuning remap would cost ~£300, and revo would be twice that, theres no way on this earth they would do that to anyone!
