Radiator/Intercooler Options?

Mack

Well-known member
Many shops have developed better tunes upto 400ft/lbs torque on stock internals and upto 500HP plus and 700ft/lbs torque with upgraded internals if you ever choose to increase it for offroad use. I will however be sticking with stock tune for guaranteed reliability from Cummins in the meantime also.

Do you have any info on what shop(s) is offering upgraded internals for the R2.8?
