So onto my next question, but first a bit of background. I ran Chuckwalla on Sunday and first session out, the car went into limp mode with a solid wrench light on the dash. This has never happened. Had to pull off to the side, shut the car completely off and restart it so that i could even drive it back to the paddock. Quick Google check was pointing at potentially a dirty throttle body. Pulled the intake tube, and sure enough there was a fair amount of oil on the blade and housing. I have a separator installed on the passenger side, however the driver side PCV hose still feeds into the OE intake tube. I rarely get much oil in the passenger side can, but it had probably 3-4 ounces in it. Is this a normal byproduct of the increased oil flow from the balancing hoses? I’ve been considering the Watson Racing Peterson catch for a while now, but it may have just moved up the priority list.

No, there's very little flow through the crossover lines. They balance pressure more than anything else, there's not an active flow through them (think of them as sitting at the very end of the oiling system, tying the two tail-ends together between heads.
For the blowby accumulation, definitely look at the watson can. Interestingly enough, I had similar issues at Chuckwalla the week before you, but I think mine to be more electric than mechanical.
