I'm getting ready to upgrade but I need some input on the three kits: Alpha 9, SPE900, P800. At this point, I am leaning towards the Alpha 9 because of the minimal turbo lag (3K) and reliability as a DD. I don't know anyone with this kit, so I am just going off of articles and data. Alpha 9 owners your input is highly appreciated. I also would like to hear from SPE900 and P800 owners about their experiences to help me decide. I would like to make my decision by end of next week. Thanks in advance!
