Take your ION Red Line to the next level with our Stage 3 Off-Road kit!

The Stage 3 kit consists of the following:
Smaller, 76mm supercharger pulley
2-pass intercooler end plate
Unique PCM which includes a calibration for the smaller pulley, an adjustable rev limiter, a 100 octane mode, and a nitrous algorithm.

Our Stage 3 kit will take your supercharged Ecotec to a whole new level of performance. Stage 3 takes horsepower output to 248 on 93 octane fuel and to 260 horsepower on 100 octane fuel.
In addition to the power increase, you'll also get an adjustable rev limiter and calibration for a 50 shot of nitrous (nitrous kit not included).
For best power, we recommend also installing a high-flow exhaust.

The PCM is equipped with a user adjustable rev limit from 6750 to 8000 rpm. The rev limit is adjusted by pressing on the throttle pedal with the ignition on and engine off. At about 50% throttle the tachometer will show the current rev limit. Pressing the throttle further will adjust the rev limit in 250 rpm increments. This PCM is also equipped with a control scheme for the equivalent of a 50-horse shot of Nitrous. The PCM will automatically provide the proper spark and fuel for A Nitrous up to 500 rpm below the current selected rev limit when the trigger is activated.
