    I've messed around with my 05 Expedition XLT a little bit. It's bone stock aside from the IMRC's being mechanically stuck open (did this for previous diagnosis of massive timing retard and have not gotten back to correct it yet).

    Have you had any luck with tuning your yet?

    i have an 04 nbs and i too would like to eke out a bit more power and mileage from this, uh, underwhelming engine. very little info out there for these things especially in stock or near stock form.
