Seeing as I have 2 E46 M3s currently with both being equipped with the infamous SMG 2 Transmission and one having the CSL tune and the other not, I figured it would be a good time to do a direct comparison between the two. This video shows how different an M3 behaves once with transmission has the CSL tune. In my opinion it's night and day and an absolute must for anyone who owns one of these cars! It will transform your driving experience and maybe even your opinion on the SMG transmission!
