Now that we have adaptive E30 E40 tunes from some vendors, and insanely stable static E30 tunes from others I would strongly advise not going meth. If you were on the 2010-2012 gen meth is awesome since we lack proper flex fuel parts... But for 2013+ running a basic E30 tune will yield more power with less reliance on external systems and external fail-safes .. it will just be less parts to plan and maintain and possibly fail. If you have good e85 stations I'd go E30-E40.
Cheers!
