We are very pleased to be a premier tuner for the 3.6 Direct Injection LFX V6 found in your 2012 to present Camaro V6. As GM V6 specialists, we know you're enthused about your V6 Camaro, and we're enthused to help you get more out of it. The benefits of an Overkill tune are straight forward: More power, more instantaneous, improved transmission performance, and proper support for your additional modifications. Best yet, with an Overkill tune, retuning support in future is included, so we'll help you each step of the way forward as you add something new.

What you'll notice:
  • Horsepower and torque gains of 15-30 on 91 octane and 10-15 on 87 octane anticipated
  • Stronger low end torque, less peaky feeling to the power delivery
  • Improved response from the throttle pedal, NO NEED FOR EXTERNAL THROTTLE BOOSTERS!
  • Increased fuel mileage possible, 1-3 MPG gains possible and will depend on your driving style
  • Fully rewritten transmission shift points will downshift with less throttle input, upshift at better engine rpms, reduce bogging around town, and improve how the vehicle feels by feeling lighter and easier to drive
  • Tuning For All Aftermarket Intakes including with larger MAF sensors
  • Tuning for Solo Performance, ARH and other aftermarket high flow cats, P0420/P0430 removed
  • Tuning for 3.91 and other rear end differential swaps, including auto trans retuning and speedometer
  • Speed limiter removed, Rev Limiter in Park raised
  • Tuning available for Supecharger Kits!
  • No Charge Retuning For Future Modifications for as long as you own your Camaro


What you'll get with your purchase:
  • An Autocal handheld tuning device, with software on a USB drive
  • Overkill 91/93 octane tune
  • Overkill 87 octane tune
  • Overkill E85 Flex Fuel tuning in each tune (if you get our Flex Fuel conversion kit)
  • Tuning support for datalogging and custom revisions
  • Tuning support for new mods as you add them, for as long as you own the vehicle


Why get an Overkill tune versus the competition?
  • Specialized in the LFX motor. From revised cam phasing, fully reconstructing spark timing tables and fully revised throttle calibration, an Overkill tune is more comprehensive than what you'll get at your local dyno shop.
  • Datalogging. You'll get your Overkill tunes but it doesn't stop there. You can scan with our handheld while driving and send that data for review and tune updates, to get a tune that's more customized for your vehicle
  • Support for your mods. Not only are we the only company with an E85 Flex Fuel conversion kit or a larger 80mm throttle body kit, but we also have the right tuning to ensure you get the most from them!
  • Retunes. With our handheld, retuning for your future modifications is complimentary and easy to provide

The only larger throttle body for the 2012+ LFX 3.6 is available here at Overkill. The factory throttle body is 72mm, as are ported units on the market. Our 80mm throttle body solution dwarfs the stock unit and will allow the your engine to breathe, improving horsepower, improving throttle response (particularly with Overkill tuning) and changes the intake note of the V6 to a deeper growl at heavy throttle.

Requires no tuning, works best when used with a ported intake manifold, such as available from JacFab. Uses a brand new throttle body with an aluminum adapter plate and stainless steel bolts. Newest kits now come with an o-ring seal!

Tip: This throttle body has a 3.5" clamping area, compared to the factory throttle body of 3". Ensure you have a solution available before installing the throttle body!

You have one choice to make before checking out, regarding our Overkill tuning service: HP Tuners Pro vs Autocal Handheld. Use this guide to help you decide!

HP Tuners Pro - This is a tuning suite that runs on a windows based laptop computer and connects your laptop to your vehicle with a cable. Overkill renders all the tuning for this supercharger kit, you're simply required to use the software to read and write the tunes to your vehicle, and provides scans, all of which is handled through email exchange. You do however have the ability to make your own adjustments, though it is recommended you do not alter our settings unless you have sufficient experience and knowledge to do so. This setup will require a back and forth transfer of files before you have your initial supercharger tune.

Autocal Handheld - This is a handheld tuner that will read, write and scan your vehicle's computer without requiring a laptop. You'll need a windows based PC or tablet with USB connection to transfer files on and off the Autocal. You won't be able to make any tuning adjustments yourself, all tuning will be handled by Overkill. Your Autocal does have the ability to be a code reader, you have the ability to take your handheld with you in the vehicle wherever you go and it can hold several tune files at one time. Your Autocal will come with a base supercharger tune file ready to load when you do your initial installation.

Stage 1 Kit Information

Our base kits come set up with 8-9psi of boost. They can be installed on a completely factory 3.6 V6 and see a 100 horsepower gain. You do not need any modifications on your vehicle to install Stage 1, comes with everything you need. Aftermarket exhaust work is beneficial but not required.

Stage 2 Kit Information

Our Stage 2 kit provides improved performance with more boost, and the required fuel system modifications to support it. A factory GM ZL1 fuel pump is a direct replacement to the factory V6 fuel pump and will provide sufficient fuel flow to the engine. The fuel tank must be dropped for installation, not difficult, but an advance installation for driveway installers. Once installed however, it's matched with a smaller supercharger pulley to increase boost to 10-11psi, providing a 30-40 horsepower additional gain over the base kit. Exhaust work is beneficial and recommended but not required.

Kits start at $5999 for existing Overkill Tune Users, $6499 and up to purchase with Overkill Tuning and Autocal Handheld or HP Tuner Suite Pro!

This is an upgrade kit for those in search of improved performance over the base kit. The base kit will run roughly 8psi of boost and is 100% bolt on friendly. In order to run more boost, a fuel pump upgrade is required. This Stage 2 kit adds a bolt in GM fuel pump upgrade to allow you to run more boost and not run out of fuel. A smaller supercharger pulley will produce 10-11psi of boost, very simple. The pump will require dropping the fuel tank for installation, or cutting an access panel from inside the vehicle. You must install the pump to run the smaller pulley!
