If you going to buy a PCM do NOT buy a ZZP PCM. You'll be playing a game of hit or miss with them if you do. There have been numerous complaints by a large number of people on the PCM's ZZP tunes and sells. Some people have even had cases were ZZP did'nt even tune for, or delete everything that they had asked and payed for them to do. Not to mention the people which had shifting problems and the other people who's car wouldn't even start once they installed it.
