Tuning boxes dont have the best reputation, it looks ok but you can tell the tune will be a generic file and not as strong as if he had a map done as the torque after remapped is only 285ftlbs and i know these can go upto 320-330ftlbs,
nick at rtech is very good at getting really progressive maps with good peak figures on these, he would be better off waiting or send his ecu off to a company and it would be the same price
