EXPLORE TUNE FEATURES

PULLEY RATIOS
Reducing the diameter of the supercharger pulley and/or increasing the size of the crank pulley spins the charger faster and increases boost for easy and massive power gains.

2-STEP LAUNCH CONTROL
Reduce 0-60, 60-foot, and acceleration times with 2-step launch control. This advanced fuel cut strategy builds engine load and boost providing an extremely aggressive launch.

EXHAUST CRACKLE
Want some disruption on demand? Then equip yourself with Exhaust Crackle for that call of the wild. Let off the accelerator, downshift, or free-rev for a head-turning sound.

E40 ETHANOL
For the highest power output, E40 is a blend of 2/5ths E85 ethanol and 3/5s 91 octane. This mix safely provides a cool-burning, knock resistant, high octane fuel.

MANUAL FAN CONTROL
Use the cruise control stalk to run the radiator fans and coolant pump at full power to rapidly cool supercharger and intake air temperatures and recover power.

FUEL DRAIN
Your iE POWERlink app and a few feet of 5/16" fuel hose make sit easy to drain tank dry of that 91/93 pump gas so you can fill with 100, 104 octane or E40 ethanol for extra fun.

REV FREE
Your iE tune increases the rev limit to 7200 RPM and 7350 RPM with dual pulley ratios. These higher limits maximize the potential of the larger powerband for a stronger, longer pull.
