The CSP 4 tune will be sent via email, and you will need an EFILive V2 or AutoCal to load the tune into your vehicle. Please select desired horsepower along with other options specified.
Further, for owners of 68RFE automatic transmission equipped trucks, you have the option to add transmission tuning. One of the major benefits of having such an electronically controlled transmission are that so many factors, such as converter lock up, line pressure, and shift patterns can be controlled electronically.
Transmission Tuning Details:
Due to firewalls in the factory ECM, you will be REQUIRED to first unlock the ECM. At the present time, the only way to do this is using a Bully Dog GT (part number 40420) tuner and the Bully Dog Unlock Cable, which is available from the menu below. In doing so, you will merely need to unlock the ECM, but not actually install any tuning from the Bully Dog. Once this is complete, you will be able to use the Bully Dog in a different vehicle, but you can only unlock one vehicle with each tuner. Another option is to use the Bully Dog for digital gauges in the vehicle that the EFILive will be installed into. Either way, you MUST unlock the ECM before EFILive can be loaded. If you have questions on this, do not hesitate to contact us.
This is a custom tuned product. In various situations, you may receive an error code when attempting to load the AutoCal onto your vehicle. In most of these situations we will need to update your stock file. If you have any issues, please contact us with error code messages available so we may promptly resolve any issues you may be having.
