I'm a firm believer, hence everyone's use and love for methanol injection.
Sweet - makes sense and certainly couldn't hurt. I'll be coming from the Springs, so Arvada is a bit out of the way, but I'll see what I can find down South.

Have you run your S4 yet? It is a DCT right? A coworker has a S4 DCT and it is a beast.
