Supercharger

[SierraHD17]

I have seen only two instances with these 11 and newer trucks with superchargers.  Both on another forum I use and both resulted in the owners pulling the blowers off and going back to stock as they didnt get them running right.  One was a Magnuson kit and the other an LSA take off.  I don't like the E78 ECM used in these trucks and with my tuning on my 17 with HP I have found tables either missing or doing other than what you write to it.  I have long tubes and a cam sitting that I could install but I don't think the truck will ever perform properly so I have not.  Personally I would not waste my time with it.
