I just swapped old iron 408 w/ ported 241 heads and 244/250, 621/615, 110 lsa cam to a new aluminim 403 w/ Trickflow 225's, 244/250, 621/615, 112 lsa cam. The old motor was tuned by professional tuner and was pretty good. The new motor is reading high 14's on the wideband all the time. I have stopped driving it until I can richen it up some. Is there a quick and simple way to fatten up the tune to make it safe to drive until I get broke in and professionally tuned again.


Thanks

high 14's is what it should be during cruise conditions

Well it should be at 14.7 when driving around and in the 12's at full throttle. I would have it tuned by a pro if you didn't know this.
