I have meth injection on my 2013 1LE with a ECS kit @ 10.8 lbs. boost. Car has been sitting in the garage all winter with about a gal. of M5 in the tank. Has anyone had problems with M5 attracting moisture ? I went for a ride tonight and car seam to have a small backfire & stumble when coming into boost. The first thing that came to mind the M5 was trash. Any help with this would be much appreciated.

It can go bad... it's quite hygroscopic and the tanks typically have breather holes open to the atmosphere. Just drain it; it will only take you a few minutes and it's cheap peace of mind. It could be the issue you have encountered as well...
