Not sure what your reservations are? the 2014 Shaker car is a 5.7 Hemi the same as any R/T. The horsepower rating doesn't change for the Shaker version, so there shouldn't be any big differences. If anything the Shaker might act as a CAI but that is a common mod that is used with diablo programing. What are your concerns?Has anyone tried to tune their Shaker yet? I normally tune all my dodge's with a Diablosport tuner, but I have my reservations about the shaker. Any thoughts?
