In my 97 mazda 626 (4clynder) I didn't notice any different in engine performance/mpg's when i upgraded from stock 80amp alt to 160amp (custom built)... Yeah... my mpg's did go technically down... but I couldn't tell.. I'm guessing it was less than .5mpg. Yaris might be more affected... I dunno... the mazda had like 120hp.
