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!

Intake Coupler Required?

The following separate purchases are suggested to match this throttle body to your existing air intake system:
  • For CAI Inc systems, purchase the Aero Exhaust 3.5" 135 Degree silicone elbow
  • For K&N systems, purchase the Intake Hoses 3.25 - 3.5" 90 Degree Reducing Silicone Elbow
  • For Injen systems, purchase the Silicone Intakes 3.5" 90 Degree Silicone Elbow
  • For Rotofab systems, purchase the Silicone Intakes 3.5 - 4.0" Reducing Straight Silicone Coupler
  • Add 2 clamps with a 4" or 102mm maximum diameter for each system, except the Rotofab which will only need one

Unlike most other LFX engines, the Camaro isn't flex fuel, however for those enthusiasts who know the benefits E85 Ethanol can provide we now offer a flex fuel conversion kit. A genuine GM flex fuel sensor from another LFX application is combined with a custom made wiring harness that requires no cutting/splicing, just a plug and play connection and add one pin to the factory computer wiring connector. OEM sourced braided steel hoses plumb the fuel supply in the engine compartment complete the kit.

Tip: Tuning is required. We have our own specific E85 performance calibration. If you have Overkill tuning, we'll provide the necessary tuning for flex fuel activation with our E85 performance calibration at no charge.
