Not a stock spec, I run SXX V2 in all of my cars except for my B44.1 which is an SXX V2 TC-Spec. I went with the SXX V2 for my 1/12th because not only does it have boost, but it also has a dual BEC so you don't need any extra shit in the car. Thanks for all of the input, I figured it would come down to some trial and error, it always does.
