Since the tuning section gets no hits I am putting this here. I went to tune a car and found out it had a dhp 1.o pcm, and my tuner would not open the file it read from the pcm. So if a car has been tuned by a dhp tuner will it do the same thing? I have an hp tuner and would like to know, before offering to tune peoples cars that have all ready got a tune from someone else with a dhp tuner.
