Thanks for the write up and comparison, futher validates what I've experienced with my Bully Dog install, website and support, all top notch thus far...still waiting to get my dyno done

 

Humm good point buddy. I think the Cobb one wouldn't (but I haven't even checked with them and my ECU code) but I was hoping Bully dog wouldn't have any type of restriction. I'll find out more info before I go ahead with ordering one of the two.
