Title: Boost leaks affecting mpg?
Post by: Big Tone on 28 March 2011, 09:12

After becoming somewhat anal around fixing boost leaks, she is now tight as!
I can definately now say that my mpg has increased sure to me keeping on top of even the smallest leak.
Has anyone else noticed this?

u will notice a different mate, as the AFR will be giving the best mixture to burn around the map. less air than calculated or less fuel then asked for will result in the afr going either lean or rich, this making it a less powerful mixture to burn.
