If you reset the ecu the MPG is gunna be crappy for a while.

Otherwise in theory an SRI should improve MPG, that is if you don't change your driving habits. (mashing the pedal every chance you get)

So regardless what what mpg the car can achieve it wont untill the ecu says so? How long should it take to relearn? this will make my third tank and ive only gone around 290mi. ALSO when i first installed the sri i was constantly getting the po171(i think that what it was) for being lean. shouldnt the ecu correct for this? Thanks for the reply

I do think a SRI makes the MPG worse. I noticed on my camry the same effect. I converted the SRI to a CAI and it became normal.
