MPG decrease after mods
Posted: January 26th, 2016
I have the 2009 accord lx-s and I added a takeda sri and a magnaflow 14832 with no stock resonator. After that, I added Techron Concentrate Plus Fuel System Cleaner and I noticed that my mpg went down from 21 to 19. I drive mainly city. Any ideas why this happened? Is it possible there's a leak in the intake tubes or something? Maybe the clamps aren't secure on the intake and it's causing an air leak? I've tried keeping my accelerating roughly about 2k rpm and my mpg is still 19 in all city driving. Thanks.
