I am selling a Quadzilla Stealth 2 215hp Race Tuner. It is not the regular Stealth 2 that only goes up to 135, it is the Race Tuner. It is rated at rear wheel power not like other chips more or less to the engine. This tuner retails for 700 bucks new! I am selling for a buddy. This chip really runs! Best tuner out there for the lb7. Asking 400 OBO shipped to your doorstep. PM if interested. Thanks.
