QUESTIONS & ANSWERS
Ask a Question-
Will this kit work with a CCS 45 hp tow tune or will the kit require modifications?
Just a tune update!

Is this part compatible with aftermarket tuning? If my truck has tuning designed for the system with the CP4 will this CP3 still work the same? Or are further modifications to the tuning required?
A tune update will need to be done by your tuner, thanks!
