Nice n clean!!!
I like to use a can of cleaner with a toothbrush. To get to those in between the gums lol

Looks very clean!!!

I added the cheapest catch can I could find to my last truck a 2002 z71 Silverado. I transferred it to my 05 Denali but need to get a bigger one. It collects alot of moisture on mine in the beginning g. Almost looks like the scary chocolate milk. Now it's the usual oil. I was having white smoke puffs when starting the denali. After changing the intake gaskets, cleaning the valve cover where the pcv valve is on, and adding a catch can, it has definitely improved.
Thanks! I used a toothbrush, but it was pretty worn out. Should have grabbed a new one. Better anyway.

Catch can saved another few ounces from the throttle body.. also cleaned the throttle body the other day, at the behest of Justin @BBPerformance.. it was filthy.

I’m really considering replacing it, but before doing so, I’m wondering about a TBSS intake / TB or something larger. Would this be worth doing?

Didn’t get it as clean as I’d like but it is a big improvement:

Yessir! Well, to be fair, I replaced the MAF first, and like 1 day before cleaning the TB, so it’s a combination I’m sure. But I hadn’t noticed until last trip to the airport, I noticed a little hesitation here and there. Now she seems smooth, and I haven’t felt that hesitation any more. Really digging the BBP tune!
