I just know what I was getting compared to what I have been getting since the swap, nothing else has been changed on the car.....I dont know what caused it to be better but I know what GXP's average in the city(15-16) stock and now mine has been at 19.5 for the longest time after the intake. If that is what made it better I dont know but its been better since then.
