At DiabloSport, we know that tuning is the optimal way to get the most out of your ride but not everyone wants to go that route. That knowledge is what moved us to design the Sprint module for GM applications. These products are designed to optimize the active fuel management feature that comes enabled from the factory on GM applications since 2005. This AFM feature is designed to deactivate 4 of the cylinders in an effort to improve efficiency. We know there are customers who love this feature due to the mileage improvements it brings and there are those who want full power all the time. Luckily, the Sprint module delivers!!
