Hey got a quick ? For yall.... I ran the beast last night and had my wideband o2 logging and got a 12.0 AFR when I sprayed the no2 and about .2 higher when on the motor... then I out smaller fuel jets in it was good in 1st but in 2nd and 3rd the car went rich. I am running 40 deg of timming no knock and with the smaller fuel jet I ran 2 tenths quicker.... now for the ? What is the best way to tune the fuel I have seen the PE-vs-RPM table and that is where I suppose you do the fuel stuff... and the AFR should be at 13 and how much are the numbers going to affect it also I have a copy of some o2 runs and the tune... any help is needed no pcm guys around abilene tx... I would appreciate it thanx...

Get your N20/Fuel ratio to about 9.6:1 and then ajust your over all a/f accordingly to hit 13.1 a/f or as close as you can get.
