Bully dog chip

I'm thinking of getting the bully dog chip for my truck. I'm just wondering if anyone on here has it and if so do you notice any power gains? Has anyone done a dyno test? And does it improve fuel economy? Also is it very difficult to install? Thanks

 

Take a few minutes to wander up and down the aisles of tacomaworld, especially the performance and tuning section. Lots of info regarding this topic on here.
Bully Dog nor any other chip/programmer are able to make significant gains on a toyota because toyota ecu's are locked down tight.
The URD UCON is the best option but not worth the money on a NA motor imo.

 

The maf calibrator has been dynoed and made 15hp on an otherwise stock tacoma. Cheaper than the ucon
