MP275 kit is CARB approved
Definitely something I left out when listing the pros of the COBB system. The AP is a great tool that all the top tuners in the industry use. Going with the Mountune kit basically eliminates the entire realm of aftermarket tuning outside of the OTS tune you get.Personally I don't think that you really save that much by buying the kits, but if that's the direction you want to go you have to decide how important warranty is to you. If you're not worried about voiding warranty, or if you know the people at your local Ford dealer and know they will work with you if you do need to use it, then the Cobb AP3 beats the hell out of any other tuner on the market IMHO, but if you are just going to use the cobb ots maps you are missing out on much better tunes by other companies like Stratified, Panda, etc. Honestly though, I don't see much value in the kits and would rather just buy individual parts and pick and choose exactly what I want to go on. I suggest do the math on the parts you want individually and compare with the cost of the kit and see what makes the most sense.
