Hi everyone, I just heard about hypermiling a few days ago and thought it would be a fun thing to try. I've read up a bunch, but there's one thing I can't seem to find a good answer about.

Wikipedia says 75-100% throttle is most effecient for acceleration, while multiple other sources say as slow as possible, and a few say inbetween. I read a couple good threads on this forum and different drivers seemed to get different results between different vehicles.

My question:
Does anyone know or have an educated guess for what will work best for a 2003 Chevy Impala? It's a mid-size car with an automatic v6 and no rpm gauge, unfortunately.

Tips on easy effective mods would appreciated as well.
