The infamous Crazy Larry returns
For years Crazy Larry was the most desired tune on the market, racers from coast to coast used the Crazy Larry tune to dominate the competition and then it was gone.

As vehicles changed and new systems were introduced from the OE manufacturers, it required the Bully Dog engineers to develop new tunes that would produce the power that Crazy Larry has been known and loved for. Now, after a couple of years, it is time for Crazy Larry to make a return, making more power than before and more power then the other guys.

Through extensive research and design, Crazy Larry is ready to hit the race track, but this time you can expect much, much more; the new Crazy Larry tunes will only be available on the new Crazy Larry GT. Loaded with functions and features that the GT is known for, but with more power!

“Race tracks” are key words here. Due to government regulations and Bully Dog’s adherence to them, the new Crazy Larry GT will be available for vehicles not registered in the US and for competition applications only. In order to utilize the Crazy Larry features and tuning, each owner must register their product to ensure that it is not a street registered vehicle.
