Wideband

cruise can be in the low 15's. 13.0-.2 at WOT, 14.5-15.0 part throttle and under 15.5 at cruise. The higher AFR at cruise will increase mileage at the expense of higher EGT's and NOx levels if it has to pass the smell test. if you can tune on the fly, that's the best way to do it as all motors are different. Best thing about a wideband is plugging it in and seeing your Carter at 12.0 at idle...no wonder it stinks! But with that cam, good luck...

Make sure you install that O2 sensor at an angle off the exhaust pipe, you dont want it sticking straight up into the pipe (on the bottom of the pipe) as it will rust out eventually.
