Looks like your airfuel richens up to 9:1 at the high rpm. Check the part of the vid where the narrator is showing boost and airfuel in relation to rpm on the dyno graph. You werent running out fuel, you actually were adding too much on the high rpm side.

unless i am missing something here the bottom line is 10:1

when i said we were running out of fuel i should have said duty cycle. it was over 100%. now i know when you lean it out it lowers duty % but not by 25%.

Well, try leaning it out and then tell us what the decrease in duty cycle is

Definitely repost numbers when you get a chance. Leaning out the top end some will get you better power numbers. Even if 10 is the lowest line, that is too rich. Your tuner should shoot for 11.0-11.5 on the dynojet.

thats what i was thinkin and then add a little timing .... 25 to 45rwhp...

i ordered 8.0ltr truck wires as mine are beat so with that and the pump and the referrecend regulator i should be able to crank up the boost to 17,18,19 i would think that would get me 20 rwhp for every psi so....that another approx 120 140 rwhp. damm that alot! 750 790 rwhp a/4 is going to get me at traps 142 145 easy. well nothing is easy
