Those of you with the SSM PowerPaks
To those of you with the SSM PowerPaks installed on your split-port vehicles, did your mpg go down? Was most of the gains you saw on the high-end of the band? Any complaints that you have?
I'm asking because I just ordered the Stage 2+ kit and it won't be ready for ship until end of April, I just wanted to know what to expect out of this thing.
