As GM 3.6 specialists, we offer the best tuning and unique products for your 3.6 motor. Our suggested modpath for the 2016+ Camaro V6 platform is as follows:







Overkill is very pleased to be a premier tuner for the 3.6 Direct Injection LGX V6 found in your 2016 and newer Camaro V6. You're enthused about your V6 Camaro and Overkill tuning is here to help you enjoy your car even more. The benefits of an Overkill tune are straight forward: More power, more instantaneous, improved transmission performance, and proper support for your additional modifications.

With an Overkill 2016 Camaro tune, the focus has been on fixing some key driveability shortfalls. The throttle behaviour is much improved, more natural feeling and more responsive. The busy transmission behavoir to upshift early and resist downshifting is fully cured. Both of these benefits while improving horsepower output throughout the engine rpm range. Best yet, with an Overkill tune, retuning support in future is included as you add something new to your modification list. You will love how an Overkill tune improves the feel and drive of your 3.6 Camaro!

What you'll notice:
  • Horsepower gains of 22 wheel horepower on 91 octane with no other modifications
  • Improved response from the throttle pedal, fixes lag and surge on takeoff, different throttle feel in Touring and Sport modes, no dead pedal feel while cruising, NO NEED FOR EXTERNAL THROTTLE BOOSTERS!

  • Tuning available for Overkill Supercharger Kits!

  • Tuning support for datalogging and custom revisions

Why get an Overkill tune versus the competition?
  • Specialized in the LGX motor. From reworking the tune on a factory vehicle in great detail to being the first to tune a supercharged LGX Camaro, an Overkill tune is far 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 is Overkill the only tuning company offering support for your aftermarket intake systems, Overkill is working to bring new unique products to this platform such as an E85 Flex Fuel conversion kit and a larger 80mm throttle body kit, and you can be sure Overkill will have the right tuning to ensure you get the most from them!
  • Retunes. With Overkill tuning, retuning for your future modifications is complimentary and easy to provide
Important Note for 2017-Current Transmission Tuning - For 2017+, GM heavily encrypted its 8-speed Automatic transmission computer modules. In order for this module to be tunable, it needs to go through an unlock procedure through HP Tuners. You can still get the engine tune from us without going through this service. If you want our Overkill transmission tuning as well, you need to go through this separate and unavoidable service through HP Tuners before we can tune the transmission computer on 2017-current 8-speed automatics. This does not affect 2016 models. You can purchase this service from HP Tuners for $199 using this link https://www.hptuners.com/product/tcm-modification-service









Note the payment options below. If you have a 2017+ Camaro with automatic transmission, you can optionally get a decrypted brand new transmission computer in order to receive an Overkill transmission tune, but you can also select just the engine tuning which will get you the power gains and adjustments for your modifications such as intake system or exhaust upgrades.

Our 80mm throttle body solution is now available as a stand alone bolt on option for the LGX motor! The factory throttle body is 72mm and very small for a modern 300+ horsepower motor. This 80mm throttle body dwarfs the factory unit to allow more airflow without restriction. We've seen up to 11 wheel horsepower gain when combined with a good free flowing larger diameter intake system. The adapter plate tapers down to the factory intake manifold opening, which can be ported for further gains if you're a handy man.

Uses a brand new throttle body, your factory unit being sent in is not required. You'll need a larger diameter silicone clamp for the larger throttle body opening; those with the AFE, K&N Aircharger 63-3094 (plastic tube) or GMPP intakes will need a 3.5 to 3.25 silicone coupler ( click here ) plus a clamp for up to 4" diameter, K&N Typhoon (metal pipe) intake will need a 3.5 to 3.0 silicone coupler ( click here ) plus a clamp for up to 4" diameter.
