JD @ 12T, Sorry to hear about this, i know how this can feel when my mate was ripped of by henry on ITR-DC2 (basically spent 5k and came back with less power and someone elses bottom end which was knackard)
Its a shame, i dont think you can take it any further apart from worn others not to go there and that will affect them, as much as they affected you.
Tp of course people are going to attack RC's, they mugged people and knew all about it! My close friend has personal experience with them and we know all about them.
As everyone says, TGM! or FONZ on here for the mapping! Guys in the US are good also, and know there stuff when mapping!
