It's with pride to be a premier tuner for the 3.6 Pentastar V6 found in your 2011-current Jeep Grand Cherokee and Dodge Durango. Overkill specializes in Pentastar performance and whether you want to improve your Durango's family hauling capabilites or your Grand Cherokee's cross country performance, we're here to support your Pentastar platform.

Special Note: I realize that most with SUVs 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:
  • Dyno tested 25+ wheel horsepower gains over factory on 93 tune, 40+ horsepower gain on E85, doubles the gains of the preloaded Diablo tune
  • Tune purchase includes 87 octane, 91, 93 octane and E85 tune (if flex fuel) 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 lower temperature thermostat, highflow cat converter replacement, intake and exhaust modifications.
  • No Charge Retuning for as long as you own your Pentastar vehicle!

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.
