Overkill's own personal 2013 Town and Country pictured above, trust the Pentastar tuning guru that owns the vehicle you do!

Overkill was one of the original tuning outfits for the Chrysler 3.6 engine and I tune dozens every month. Your minivan can benefit from Overkill tuning, just as well as any Charger or Challenger! For the vans, I focused on the 87 octane Overkill tune to provide the best performance gains without paying for premium gasoline, however you can also get exception performance with Overkill E85 ethanol tuning as most 2011+ Grand Caravans are flex fuel capable. Gain 15-20 horsepower on 87 octane, 30+ on E85 ethanol along with noticable torque improvements to go up inclines with a fully loaded cargo or passenger compartment, or towing a trainer. Improved transmission life and improved shifting performance! Cooler running engine and transmission, improved throttle control, horsepower and torque gains, all available with Overkil tuning!

Highlighted Features/Benefits:

Improved Transmission Performance and Life Expectancy!

Everyone complains about the transmission shifting and the short transmission life in these Chrysler vans, and don't touch that Eco button! Part of the issue is the early upshifting to higher gears and reluctance to downshift back to lower gains, causing the transmission to drag the van along at low engine rpms; this puts strain on the torque converter in particular, which has a high failure rate in the 62TE transmission, and it ruines the performance of the vehicle. Overkill tuning remaps the throttle controls and affects the transmission shift pattern, so not only will the transmission hold the gears longer during normal acceleration, it will also downshift much easier around town, on inclines and on the highway to pass a slower moving vehicle, without bogging down and straining the transmission in a high gear. It also corrects the jack rabbit throttle response, making the van easier to drive and accelerate smoothly. Once you get used to the new throttle pedal feel, it will feel natural and the benefits are significant.

HP Tuners Suite: Tuning for your Caravan is provided through the HP Tuner's suite. This tuning suite requires you to have a laptop or tablet running Windows. You'll be required to read and write the tunes to the vehicle using the suite but all the tuning work is provided from Overkill. A few clicks and key turns and you're tuned in a matter of minutes. The suite is yours to keep ($399 value!)

Important Note for 2015 and newer Tuning: For 2015 and newer Chryslers, a computer modification is required to become tunable. You must remove the computer from your vehicle (15+ Grand Caravans, the computer is accessed behind the driver's side front bumper and wheel well) and send it to HP Tuners for modification. This is a $250 charge that involves a separate transaction with HP Tuners, it is not through Overkill. There is no way around this!! I wish there was, blame FCA. Once you get back the computer module, Overkill will be able to write Overkill tunes using the now unlocked factory programming from HP Tuners.

*New Product* Seat Rail Extensions - $199

As a Town&Country owner myself and a big tall fella, I could not get comfortable in the driver's seat without some more legroom, so I did something about it and now I can pass along this solution to you. These seat rail extensions are solid 1/2" thick aluminum, they go between the seat rail and subframe and move the mounting position of the seat backwards providing 2.5" more legroom which makes a considerable difference! Sturdy and powdercoated satin black to match the subframe, comes with hardware required and is a straight forward install. Special note however, once installed you won't be able to stow the 2nd row seat behind into the floor, the bin however is still accessible. Can be used on either front seats from 2008-2019 on Caravan and Town&Country (I don't know if they for 17+ Pacifica yet, sorry).

Air Intake System - From $149

I made up this intake system for my own Town and Country and am happy to replicate it for you. This tubing replaces the factory air resonator and the ribbed accordian tubing with 3.5" silicone and aluminum tubing that provides a noticable improvement in throttle response and power improvement throughout the rpm range, even when coupled with the factory air filter housing. As an open cone, the intake becomes loud and throaty, and does further improve performance, however with the factory filter housing the intake remains fairly quiet which satisfies the van's family hauling duties. You can always add a cone filter later as desired

"Intake as pictured" comes with tubing between the throttle body and air filter housing, including all clamps and a brand new preinstalled intake temp sensor as they can be tough to remove and easily broken asking you to reuse your factory one so I go to the extent of preinstalling a brand new sensor. Price - $149.
"Add cone air filter" as it sounds comes with a K&N cone air filter to replace the factory air filter housing. This filter also has a prefilter wrap which extends the filter life and makes cleaning considerably easier. Due to how loud the open cone filter is on this particular van, this option comes with both the K&N cone air filter but also the connections to the factory air filter housing, so you can swap and choose as you desire. Price - $229.

Want some improved performance from your 2011+ Grand Caravan, here's my suggestions:

The factory Pentastar fuel injectors are flex fuel but they're undersized when using E85 once you've added our tune. Running out of fuel at higher engine rpms costs you horsepower and brings up engine safety concerns. These larger 39# fuel injectors replace the factory 32# units to provide adequate fuel supply. Once installed and tuned, they will operate like factory injectors, won't negatively affect fuel economy, can be run on gasoline or E85, but will improve horsepower by up to 17 wheel horsepower on E85. Fits all years of Grand Caravan, Town&Country and Pacifica.

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

Want some easy horsepower? The lower intake manifold from the Pacifica's updated 3.6 Pentastar motor is an upgrade to older Pentastars. It features much smoother transitions and doesn't have the pinch area that we used to port out of the older Pentastar manifolds. Dyno tested, this is worth a quick and easy 10 horsepower improvement.

This manifold can be had using part number 5281803AA in the $130-150 range from a Chrysler parts supplier or your local dealership, just be patient if they're backordered. Since the fuel injectors are in the lower intake manifold, great chance to upgrade to the 39# injectors for E85 use while you're in there!
