I have a quick question about a pcm. I have a 99 Trans Am that is currently tuned with HP Tuners. I'm in the middle of a build right now and he is about 3 hours away so he emailed me a start up tune for it. I know I will have to purchase two credits with my HP Tuners to write the tune on the car, but will that change him being able to tune the car with his HP Tuners setup? I guess what I'm asking is can two different HP Tuners accounts have a license for the same pcm and both be able to tune it? Or will I have to buy credits again after he tunes it with his?
