comes with 74 pri, 84 sec, no rear power valve, they do have 4 window power valve in pri and changable restricters for the power valve circut. right now we are to lean @ wot and to rich @ idle, working on idle air bleeds as well as idle feed on idle side, power valve resticters and jetting for WOT, cruise is good, and we are using a wide band in #5 header tube and now works like a champ...

Interesting Idea that I will play with once I get mine back in the water. I bought a Pro Systems 950 and wished I had bought a QF. I'm working off of spark plug color since I don't have an O2 option. I've been tuning for 2 seasons. It would barely run when I got it. I've heard good things about the new Holleys from guys who took them out of the box and checked them on the dyne and the numbers where spot on, just haven't heard as much about QF.

I have not yet, as they will effect the cruise AFR as well, so trying to dial it in the power valve channel and secondary jets, but I have air bleeds ready if need to...waiting on the idle jets now from summit...will clear PM

Agree, but those of us running Lightnings apparently have no option for this, as has been documented on a couple of threads. Would love to have one on my boat, but too tapped out to spring for a set of Stainless Marine manifolds, along with the transom surgery that will be required to relocate the openings to make them work. Wish there was an easier way.

EZ, I'm too lazy this morning to go looking for your thread on the O2's and the Lightnings. Can you elaborate on the tubes? Feel free to PM me if you want to take it offline and avoid further derailing the OP's post. Thanks.
