I have a compucar dry kit. Its called bottle in a bag and it only takes about 15 min to install. I've only used it at the track and with a 125 hp shot it drop my times 8 tenths of a second. Thats not to bad, and I didn't spray off the line. It feels like a turbo, and its easier on the internals. Hp Performance in Orange Park, Fla recommended this kit when I had my car tuned there.
