Does EFI cleaning helps with mileage?

My 'new' tires (about 15,000 miles ago) are the same model as my previous set, but the max psi is now 40 rather than 44...not really germain since anything over 38 (which I sustain), personally...just me, feels like driving on rocks on these tires...great tires though...got 85k out of the last set. When I eventually say goodbye to this Yaris (for a new Yaris), I'll probably use AMSOIL right off the bat, and change the exhaust as many of you have.

No problem

Which stock tires did yours come with the Eagle LS or the Potenza's?

I don't mind harsh rides, 205/40/17 (stretched in the rear) and 51 psi (cold).
