THIS TURBO ACTUATOR IS SELF-CALIBRATING.
NO CALIBRATION IS NEEDED.

IMPORTANT NOTE. This part is non-returnable once product box seal is broken. It is your responsibility to properly diagnose a turbo problem before ordering. Improper installation can and will damage the turbocharger. Also, if your truck has around 200,000 miles or more, then the odds are high that you need to replace the turbo as well. It's not worth ruining a good actuator with a well used turbo that has 200,000 miles of soot build up.

Before you buy, check to make sure the gear that the actuator moves on the turbo is free. If this gear cannot be easily moved by one finger, you will need to replace the turbo. If you feel any resistance do not order this part. If you do feel resistance it will cause this actuator and any other actuator to fail.

* * THIS PART CANNOT BE RETURNED ONCE BOX SEAL IS BROKEN. IF YOU HAVE CODE P226C, THIS WILL NOT FIX THE PROBLEM.

With the Variable Geometry Technology (VGT) turbocharger in the '07.5-'12 Ram Turbo Diesel trucks, everything changed when it came to servicing it. To work on it you needed training, expensive tools and you couldn't test the actuator, so as a DIY-er truck owner you were left with replacing the turbo which is expensive.

City Diesel worked to fix this. Step one was to develop an actuator tester that anyone could use. Shortly after they released it, more affordable rebuilt turbochargers started showing up. However, there was still a problem because the actuator has to be calibrated to the turbocharger and you were not able to simply replace an actuator. This means you either have to pay a fee to get the actuator calibrated at a shop that has the correct equipment (average price $200) or buy the entire turbocharger even if the actuator was the only problem.

The cost-effective solution: the creation of a new actuator. It is what we call a half-shell: you replace all the electronics, including the circuit board and motor, and reusing the half of your actuator that only contains gears (the "gearbox"). There is no calibration required and no complicated installation. Again, what this means to you is that you have a viable, cost-effective option for replacing your actuator when you have a problem.

Cost effective solution.
No need for expensive tools or a trip to the dealership calibration.
It wipes the vanes/self-testing on every key cycle, preventing soot and carbon buildup.
The actuator motor has almost twice the torque: This makes it more difficult for the vanes to freeze up and gives you faster throttle response.
The actuator was designed from the beginning to work well with EFI-live aftermarket tuners.
Does not interfere with exhaust brake operation.
Replacement actuator to turbo mounting gaskets included.

BEFORE YOU BUY: Check to make sure the gear that the actuator moves on the turbo is free. If this gear cannot be easily moved by one finger, you will need to replace the turbo. If you feel any resistance, do not order this part. If you do feel resistance, it will cause this actuator and any other actuator to fail.

Compare the actuator installed on your truck to the images in the 4th photo above. Some customers with 2007.5-2012 trucks have found that the turbo on their truck was replaced at some point with an OEM turbo from a 2013-2018 application. (If your 2007.5-2012 model year truck does have the 2013+ turbo installed, then order the turbo actuator for 2013-2021 application - part number CM-ACTKIT2013).
