More power increases the chance of something going wrong and since being the fastest was not something i cared about is why I'm happy just having my car faster than stock and more fun to drive. I can only speak from my experiences but I have had a VF system on 3 cars in a row now and my experience with them has been great. From pre purchase to install and then after they have been very responsive to any questions. And like I said before, no issues and no lights. But yea I think some bugs still being worked out on Performante system, was talking to a friend this weekend about problems on a Performante install. I'm sure it will get straightened out
