Begin broken record post... One of my co-workers recently bought a 2002-is ZX12R, lowered, stretched, bling lights, NOS, etc... Engine is definitely not stock. He took it to Brian (after we had to shake out a problem) and got a pretty decent increase in power (169.7 I think was the final number) and the owner said it runs a LOT better! I will continue to send people to DTM! end broken record post.
