HP Tuners Suite: Tuning for your GXP/Sport is provided through the HP Tuner's suite. This tuning suite requires you to have a laptop or tablet running Windows. You'll be required to read and write the tunes to the vehicle using the suite but all the tuning work is provided from Overkill. A few clicks and key turns and you're tuned in a matter of minutes. The suite is yours to keep or we do provide a repurchase option once you're tuned, email for more details willoverkill@gmail.com.

Another great and inexpensive way to get Overkill tuned is through a computer module exchange service. Overkill has the ability to flash the engine computer module with our Overkill calibration. Once ordered, we take a spare computer module, same hardware that's currently in your vehicle, and first flash it with GM's own programming system using your VIN to retrieve the newest GM factory tune. Overkill tuning changes are then applied. You recieve that module and install it in place of your existing computer module. This changes the engine tune only but gives you a good boost in acceleration and allows for programming for our MAF upgrade. You can send back your factory computer for the deposit refund.

Tech Tip: This requires physical installation of the computer module, and a key relearn procedure that takes 30 minutes to perform (but only a couple of key turns in that timeframe, nothing difficult).

This is the only intake on the market for the Torrent GXP and Equinox Sport. We also do another thing noone else does and that's upgrade the MAF sensor. The factory sensor is small and restrictive. This complete intake system replaces the small factory tubing, MAF and factory airbox with larger 3.5" silicone tubing, our larger MAF sensor, and a large cone air filter that looks great and performs great. This setup requires tuning; if you order an Overkill tune at the same time we'll tune for it, or have Overkill tuning with HPTuner suite you'll receive a no cost update.

Tech Tip: This intake will also fit both the factory throttle body and our larger 76mm throttle body offering!

Available exclusively at Overkill is the only larger throttle body upgrade for the LY7 3.6 engine. Not a machined or "ported" factory unit, this is a true larger throttle body, 76mm versus the factory 71mm. For your SUV, the gains are simple: more airflow at all throttle positions, significantly better throttle response, bolts right on with no wiring or manifold modifications required; inlet porting on the manifold is suggested to maximize the improvement in airflow but not required. No tuning is required for this upgrade!

Tech Tip: You may need a larger coupler to fit onto this throttle body compared to the factory throttle body. This setup will work with our intake system.
