used is the only way to go now for a dhp. tiny tuner is on line for down load, it might be in that link i posted with the drop box link too. you want v 1.9. it shows the cat diag stuff.

if it came down to it you could ship me your pcm and i could delete the cat test and make it a canned tune if you wanted for a small fee and shipping back.

that offer stands for you or anyone else looking for a cat test delete.
