Idle A/F with versa nd 96lb... outcome?
Very few visit the fueling forum, but since most folks with bigger HO are forced induction, I am hoping more people can chime in here than in the fuel section.
I am about to order injectors... I will be runng HP/EFILive (undecided) and am using a VersaFueler ... are people here able to get the idle and transitions in a decent A/F ration area? Would it make the tune /idel easier and perhaps any better with 83's rather than 96's? or not really....
Thanks!

When I bought my Versafueler, I talked to LJ some on the phone. He said that the idle pw on his 72's was over 1 ms, but with the 96's it's under 1 ms and 1 ms is the lowest duty cycle the ECM can command. So, with the 96's, they will be running at 1 ms and it will still be a little rich. Based on his advice, I chose the 83's and it runs 1.0 - 1.2 ms at idle. Hope this helps.

I can the get a/f numbers to come around but still having drive ability issues and gas mileage is still horrible. The is for sure running rich regardless of a/f numbers but upon leaning it out more it starts to run like it is lean hesitating, stumbling, etc....
I may have some injectors issues i am starting to think. Time will tell i guess.
