Hi guys, ive heard that on the l67 you can swap the supercharger for a TVS system, which runs more efficiently.
Does anyone know if this is still an option on our cars? If its not reasonable to get or the parts are not made any more, ill just go turbo. I really like the way a supercharger reacts, (no spool time etc). If it is available, where do i get it, and what sort of power gains is it usually worth?

thanks
