Worth every penny : tune, s1 cam, hi comp piston, dhm head, intake, and exhaust
Did a quick build for an endurance race. Excellent quality and performance. Great bang for you buck with quick turnaround and communication!

USPS suck. They delay my shipping of ECU back to DHM. But once they got my ECU, it was reflushed, and was back out to me in few hours. Haven’t installed it yet, but im sure its good. Service is wxcellent as well. Highly highly recommends them
