Hey Guys,
Here's my swap.
2007 Escalade L92/6L80E into my 1968 Bel Air wagon.
I upgraded to the LS3 intake, injectors, and MAP, have true dual 2.25" exhaust(was already on the car), 2010 Camaro manifolds, 3" Aluminum Cold Air with only 90* bend.
I tuned for the LS3 injectors and map but I'm seeing 15-25% trims adding fuel.
My PVC(in ref to other recent posts about PCV) routes from each head cover to a breather can...not tied into the intake manifold at all.
So my questions is, can someone verify my tune for the LS3 injectors and map. And how much affect would a open crankcase breather system have on my tune....i.e. is the vacuum in the manifold sucking air through the crankcase and causing my lean condition?
I have verified with my wideband that the ECU is correcting to 14.7:1...so no issues with my narrowbands.
