Product Description
Michigan Motorsports Mail Order Tune
Gen 5 2014-2018 Style PCMs
5.3L 6.2L LT1 LT4 L83 L86 L8B
Once you add performance modifications to your vehicle you should have your PCM tuned. This is especially important if you have upgraded to one of our camshaft packages. Purchase our mail order tune and we will send you a questionnaire regarding the details of your vehicle. Then you will be provided with a custom programmed PCM to match your vehicle and modifications.
Unlike the Gen 3 GM vehicles, the Gen 5 GM vehicles employ a separate control module for transmission control (TCM) that is calibrated independently from the ECM (Engine Control Module).
Original ECM/TCM may be removed from vehicle and sent in for bench programming or select to have one of our ECM/TCM sent to you. If we send our ECM/TCM then there is a core charge of $125 added to the price. If you return your original ECM/TCM the core charge will be refunded.
*2019+ Silverado, Sierra, Tahoe, Yukon, Escalade will be done via email tune only. We are not offering mail order tunes for those PCMs at this time.*
- Mail order tuning is available for customers in the continental US only.
Choose one of these two options-
- Send In your PCM: Remove the PCM/TCM from your vehicle and send it too us along with the completed questionnaire. Once we receive your PCM/TCM we will program it based on your vehicle and modifications. We will then ship the PCM/TCM back to you to be reinstalled into your vehicle.
- Purchase a tuned Core PCM/TCM: Fill out the questionnaire and email it to us. We will program one of our PCM/TCM cores based on your performance modifications. We will then ship the PCM/TCM to you to be installed into your vehicle. Once you install the new PCM/TCM you can return your old PCM/TCM for a $125 core refund. Please note that our purchased cores are not new PCMs. They are used cores that we test to be fully operational.
This is the details that go into each and every calibration:
- Performance calibrations maximize performance and mileage while retaining that stock drivability.
- MAF (Mass Air Flow) and Volumetric Efficiency tables optimized.
- Air Fuel ratios optimized for wide open throttle operation
- Stoichiometric ratio set for the ethanol blended fuels that are found at the gas pumps these days.
- Timing tables carefully and efficiently calibrated for maximum performance and driveabily for 87, 89 or 91-93 octane fuels. Most aggressive timing maps will be able to be calibrated when the customer uses premium fuel.
- Idle airflow, fueling, timing to name a few among other parameters will be gone through more extensively on vehicles with aftermarket internal engine mods such as camshafts for nailing down that good drivability.
- Torque management tables are relaxed. Torque management can be overly aggressive in stock form hindering performance.
- Improved throttle response from reworking a collection of different parameters within the calibration.
- Transmission calibration is completely optimized throughout. We are getting rid of those “lazy” slow shift times that can be found in stock form. Extended shift points to match the extended rpm range for vehicles with aftermarket camshafts for example. Torque converter tables optimized for aftermarket stall converters.
- Speedometer and transmission re-calibrated for aftermarket tire size and gear ratios.
- It generally takes 3-4 business days to custom program a PCM and ship it.
- Please note the following on our Core Charge Program. PCM's returned for a core refund will be tested to verify it is a good reusable core before a refund is issued. If purchasing one of our core PCM's we ensure that the PCM is fully operational but we don't guarantee the cosmetic appearance.

PCM with mail order tune
Hello. I ordered this part because my truck is in the shop having the engine rebuilt due to the DOD failure. I wanted to have this updated / tuned PCM ready for the service center when my truck is back together. The team at Michigan Motorsports expedited the part to me with the updated tune ready for my truck. I haven’t used it at the time of this review, so this is based on the great service I was provided to get this to me as quickly as I asked for it. They did a great job and I can’t wait to see how my truck performs based on the parameters and equipment mods I provided to the team. That being said, I’ve ordered several parts over the past few weeks and have been very pleased with all their service. Thank you for everything!!! Jay
