850s and just an AFC and FPR

[liquordrunk]

okay the only reason i have 850's in my car is cause my 550's didnt have spacers and i had to move the car of it was gonan get towed..
The ? at hand is i have my SAFCII at hi-throttle to -50 all the way and it still runs rich which is okay its like(10.2)=WBo2 at WOT.. but it idles like shit now would it be a good idea to turn down my FPR to like 35psi instead of 39 to help lean it out a little

You can do that but it will still run like crap. I'm surprised it even idles at -50% across.

Why not just get the "spacers" and put the 550's in.
