It's with pride to be a premier tuner for the 3.6 Pentastar V6 in your 2011-15 Dodge Journey. We know that enthusiasts sometimes need that family vehicle, and the Journey is fortunate to be blessed with a great engine since 2011. If you're ready for a big boost in performance from your family or business hauler, we're proud to support your ambitions with Overkill tuning.

Special Note: I realize that most with Journeys will be interested in running regular octane fuel rather than premium fuel. Its with this thought that I can assure you the performance gains from Overkill tuning on 87 octane are worthwhile! Significant time has been spent on engineering our 87 octane tune to provide the right balance of performance and fuel economy. Features/Benefits:
  • Gains of 15+ Horsepower on 87 octane tune, Dyno tested 25+ wheel horsepower gains on 91/93 tune
  • Tune purchase includes 87 octane, 91/93 octane and E85 tune (if available) calibration files plus custom revisions based on scans for your vehicle
  • Significant torque gains in the mid-range
  • Improved throttle response and feel, smoother acceleration at all throttle positions
  • Fuel mileage potential is improved (3MPG improvements reported on 91 octane)
  • Reprogramming available for other custom modifications including our ported products below, intake system and any exhaust modifications.
Watch a 2015 200 go from a 6.0 second 0-60 time to 5.0 second time with Overkill 93 Tuning, Ported Manifold and Throttle Body







HP Tuners Suite: Tuning for your Journey is provided through the HP Tuner's suite. This tuning suite requires you to have a laptop or tablet running Windows.

The suite is yours to keep or we do provide a repurchase option once you're tuned, email for more details willoverkill@gmail.com.

The only TRUE larger throttle body is proudly available from Overkill Motorsport. Rather than porting the factory throttle body, our kit adapts a true 80mm sized throttle body to replace the factory 74mm unit. Dramatically improved throttle response, improved breathing and horsepower at higher rpm, and a throatier engine note will all be noticable. Works well on the factory intake manifold, and even better with inlet porting to match.

This kit includes:
  • 80mm brand new throttle body
  • Our machined aluminum adapter plate
  • Plug and play wiring harness adapter
  • Stainless steel fasteners
  • A custom made gasket throttle body gasket
Tech Tip: The factory throttle body has a clamping area (where the tubing attachs) of 80mm, while this throttle body is 87mm. You should have a solution to clamp to the larger throttle body ready to go beore installing. The factory tubing will NOT fit this throttle body.









The factory Pentastar fuel injectors are undersized when using E85 once you've added a tune and breathing mods. This costs you horsepower and brings up engine safety concerns. These larger 39# fuel injectors replace the factory 32# units to provide adequate fuel supply and will be worth 10 or more wheel horsepower on vehicles running the Overkill E85 tune. They are from the same line of fuel injectors made by Bosch as the factory Pentastar injectors. Once installed and tuned, they will operate like factory injectors, won't negatively affect engine operation at all, and won't decrease fuel economy.

Tech Tip: Tuning is required, I repeat, tuning is required! Overkill tune users can receive a no charge retune for these injectors. Also, these benefit flex fuel vehicles while running E85; these will run on gasoline just fine, but are not required for setups that use gasoline only (non flex fuel, or you never fill up with E85).
