I have been looking at the 6lb magnuson set up for my '10 R/T which has about 108k miles currently on it. The motor seems to be in good shape and has new plugs,, o2 sensors, newer timing chain from the recall a few years ago; etc. I won't be drag or street racing it much if at all, I am more interested in regaining the power loss of being at 5500 feet. I know the base maggies are the easiest SC on the 5.7 hemi's so any issues to consider or upgrade if I go with an FI setup with higher mileage car? I will be doing the install myself...
