4x4le

It will work better than running on a stock ecu. Not saying it wont be problamatic though. We have an entire box full of peoples jwt, enthaply, mines, emance ect. boards and there is a story behind each one.
Idle always sucked, or mpg was bad, or blew up motors or detenation was audiable, or there was a lean spot that was always there ect.

Things like this can be expected from mail in tunes. The best way to tune an ecu is on the dyno with someone qualified doing the tuning.
