4.30s in an auto give no advantage over 4.10s in a 5 speed. The autos have a taller 4th (and final) gear than the 5 speed which is why they were geared lower (and maybe to help acceleration?). Toyota eventually went to 4.56s with the auto 4cyls with the 28" tires to make up for the gap.

But, with that said I think it wouldn't be that bad. I would say leave it in 3rd unless you are going downhill, and leave the ECT power-mode on. The torque converter will make it better off the line than the 5speed. But don't expect phenomenal gas milage.
