Send In/Exchange Options and Core Refunds For Tuning

Send In Program

As the name implies, you send in your PCM to PCM of NC. The vehicle will not be drivable during this period of time. Sent-in PCMs are our first priority, and are typically shipped back out the next day. No security relearn or CASE relearn is required. NOTE: Some vehicles will also have a TCM (transmission control module). If you do not know whether you have a TCM or not, call us at 704-307-4227 to find out. If your vehicle does have a TCM, we will need both the PCM and the TCM so that we can tune the engine as well as the transmission for you.

Core Program

In the core program, we send you a tuned core PCM (and TCM if applicable). We start by using GM software to program your vehicle’s VIN & calibration, and then tune that file. Once you receive the core, you may send yours in back for the core refund, or retain both modules. If you choose to send in your stock PCM/TCM for the core refund, it must be postmarked with seven days of receiving the tuned PCM. The core program requires a CASE relearn and security relearn also.

Loaner Program

The loaner program sends you a stock PCM/TCM to borrow so that you can send in yours for programming. When we receive your PCM, we tune it and return it to you, and then you send in the loaner for the core refund. The loaner PCM will need a security relearn, but there are no CASE relearns required. NOTE: Expedited shipping on loaner programs only covers one shipment. To upgrade both shipments to express, please contact us!

 

PCM/TCMs MUST be in good shape aesthetically and not have any damage or we will not accept them for core returns. 1996 PCM’s are not eligible for core return.
