mate, i dont blame you for not trusting tuners as who do know who to trust and your right it is your car.....but you are the typical no brain rs turbo owner with no clue!!

missus drives an rs turbo , we have had it 13 months now and it has been ultra reliable running 190hp , so dont talk shit saying they are un-reliable.

maybe its the £100 engines you are buying

back to your question , are you sure you can hear pinking at 125 , cause i cant even hear people in the back at 80mph
