why are so many ppl selling their power pup bully dog in the market place section? don't they work as advertise? not enough power gain?

 

A few people did dynos and found a slight loss in power.

I have not yet gotten around to a dyno but I'm not unhappy.
It's definitely provided a 2 MPG improvement, you can set shift points and top end, you can advance your timing and pull error codes.

There are other tune options that some are currently persuing.
I may as well... in the Spring.
The modding dept is closed for the winter

 

im selling mine because i need new tires
