Just checking with other HEMI owners out there.. Before I installed the CAI I was avg 10-11mpg, all city driving. After the intake I was at 12.2-13 all city and was for awhile.. Now Im avg 10.5 at best, Im thinking its the heat but curious to see what others are getting. I do have a heavy foot but to drop that much with the same driving????? No codes, new OEM plugs, any ideas or is everyone else close to this during the summer
