E90/E91/E92/E93 (2006 - 2013)
So I'm looking for a tune for my 11' 335i. I'm between ESS, Cobb, and the JB4. Right now I'm leaning JB4 because of the great reviews and price.
I was hoping to get some opinions on any of the tunes and what you guys would recommend. So if you have any experience with them I'd love to know...
