| Personally I think that you would be better off with a PPE tuner. I have ran both and in my opinion the Bully Dog stuff is a little rough around the edges. Shifting is alot harder than what I have seen with PPE stuff. The defuel is very harsh. The crazy larry tune is a rough tune in itself. I think they have made some changes to it but last time I knew, it had some serious timing rattle. Hope this helps.
