I have it. Sounds great when I had it installed there was no cutting/splicing just joining of the wires. I have heard bad stories from not achieving the mentioned gains or even losing power. I haven't dynod my car so I dont know, but I have felt a slight bump in acceleration. After I get my exhaust I will have to dyno the car and see what kind of gains I get. If they are crappy I will put back the stock air box and wait for a drop in and/or JoeZ intake...
