DiabloSport performance tuning with 93 octane can yield anywhere between 15-40 horsepower (measured at the wheels) and about the same in Ft/Lbs of torque (Some applications gain more or less, depending on engine size and platform). DiabloSport’s tunes modify spark and fuel tables, throttle response, and shifting along with other important engine parameters that increase performance and economy. DiabloSport’s tunes can also be user customized to take aftermarket bolt-ons in to account! Here is a list of the tunes that are generally available on the inTune:
93 Octane “Diablo” Tune- 15-40 HP*: This tune is designed to get gas vehicles their maximum HP/TQ and Drivability Gains. It should increase fuel mileage by about 1 MPG as well!
91 Octane Performance Tune 13-35 HP*: This setting is designed as a “premium” gas setting in states where 91 octane is the maximum available. This tune increase Power and Torque!
87 Octane Performance Tune 12-30 HP (Trucks)*: This DiabloSport tune is designed to get your ride the maximum performance and economy available on every day pump gas. While this tune may not make as much power as the premium tunes, it still does wonders for the drivability of your vehicle.
MPG Booster Tune- add 2-3 MPG Economy*: The MPG booster tune is available in late model Dodge and GM applications that feature “AFM” or Active Fuel Management. This feature is not designed to add horsepower, but puts supported vehicles in to eco mode earlier, and takes them out later for big increases in highway MPG. *Not all vehicles are equipped with factory AFM.
Factory HP Tune: This is the factory vehicle setting but it allows for modified parameters like calibrating the vehicle’s speedometer for aftermarket gears and tire sizes, or removing a top speed limiter.
