Google it. Look at all the failures that their PCMs have "likely" caused. I'm on my 4th Grand Prix and got my first in 2006. In the past 5 years of forum time, I can tell you that it is not a PCM I would run my car on for any extended period of time. Maybe after a build to get to a dyno shop or someone who could tune, but that's it.

In my personal experiance, I was having issues with my tune, tired to purchase an .hpt file with their tune. I paid upon ordering a few days before I wanted it in my car. They charged me shipping, so I asked for that back since the file was to be e-mailed to me. I after days had not received the file, which on their site says they ship within 24 hours of purchase. I asked for a refund and they refused to give it to me saying that paypal wouldn't allow it and that they tried to get ahold of me about it. I never got e-mails in regards to it, so not only did they lie to me, I had to file a claim with paypal to get my money back.
