Not sure what it is, but its claimed to make 585rwhp and 585 rwtq with only a CAI, TR6 plugs and a tune. NO pulley change, all stock pullies and stock "snakebitten" blower only. $1495 snakebite only. + $750 for tuner/cai.

Dyno run 11 is the snake bite. The other numbers are the TVS blower on there.
