I've looked at all the other power adders and once put on supposedly they don't cost more money, but they're always running like a blower or a turbo.. I just took my car out yesterday for the first time and what seems like about 3 months I believe and just on the motor LOL I didn't need any more power on the street by a long shot... That dual quad stroker has way more than enough power to get me in big big trouble... I think the nitrous is going to be fun just to see what happens kind of a "watch this" moment...
