Re: aFe or Volant w/ Gibson Exhaust?
That is awesome you get 22-24 mpg highway... That is the highest I have ever heard of. He means that if you get intake and exhaust without addition tuning it is a waste of money since your computer will just recalibrate and take away the initial gains you feel after installation. The diablo or superchips helps feed for fuel and air into the combustion chamber, increase engine efficiency and power... Thus your 22-24 mpg. But be honest... You must be driving miss daisy to get that kind of mpg... Jk.
