First time post, first tune... Cobb Addict!
First post. Just got a 2008 135i. Cobbed it and must say I am amazed... No issues with the install, took some time and reading to figure out the beta non beta thing. However I am running v300 for 2 weeks now and had zero issues (no codes, no nothing!) and the car is a beast! I cannot see how any other version was better...not planning on trying them, just waiting for final non beta version of the v30x
I had a number of bimmers before, never tuned so I just figured out that super car performance came in under a grand mod and 20 minutes in the driver seat watching it do its thing!
