Seems like the stuttering is related to my battery voltage dropping under load.

Any help?
I took a log in my brother's e85'd WRX and his battery voltage only dipped down to 13.2 under load in the upper RPM's. Guess I'll have to try a new/different alternator at this point as I'm running out of possibilities.

Does anyone know exactly what the battery voltage option in Romraider is measuring?

Edit--Both pulls were done with no accessories/lights on.
