I have a few questions about hp tuners
1, If I open a pcm for a 99 camaro, does it use 2 credits each time i go into it or is it open for good?
2, If I find out it was locked by a previous tuner, how do you get it unlocked?
3, Is it better to tune on the track/street or the dyno?
4, Is it fairly easy to use and is there a place where I can learn what each function does?
