What a difference speed makes. I usually drive 75-80mph most of my 250 mile trip and have been averaging about 15.7mpg. This time I was doing more 60-65mph and my mileage was a whopping 16.7.

I agree with Doc Olds - the PCMforless make a big difference with driveability as well as mileage, but it did take a few weeks for me to see any consistent improvement.

 

i have done 2 tests so far,stock intake i got 15,w/ k&n cai it was 18,but the k&n has to come off,the ol lady says she cant stand the sound,so it is in the for sale ads,so now,as soon as my regular filter comes in,i will try that
