I don't have a kit on my 12 valve, but my friend is running a 96 12 valve with it and an 02 powerstroke and both are bully dog systems. He absolutely loves it on both trucks but he had to put a bigger turbo on his powerstroke but he also added nitrous so that probably played into that turbo. When I drove his 12 valve all I can say is wow! The throttle picks up fast and you can really feel a difference right away

I dont have propane. From what i hear its mixed feelings about it. Yes you get more power, but it also raises your egts. It just depends on what exactly you are looking for. I hear a lot of good of CNG if its available in your area I would probably get that, but the setup is way more expensive than propane.
