Two weeks later I'm still sorting out bugs in my new setup. I just got new O2 sensors because one of my old ones would rattle when you shake it(and cause the comp to throw a code 41) and then it ran 100% better, almost stock but with alot more power. Later I put 24lb injectors in also and what I think is a 24lb calibration tube for my 73mm C&L. I say "think" because my meter came with it(used) and was determined to NOT be a 19lb tube, which I needed at the time. I got the right tube and kept this one. My problem is now the car has a real bad miss like a plug wire is off(and just so you know, it isnt). The only change was 24lbers and the tube. I suspect that either an injector is bad(used set off Ebay) or I have the incorrect sampling tube. I'll run a cylinder balance test tomorrow to see if its the injectors.
The tube on the other hand I've been trying to ID for a year or more and no one seems to be be able to offer a striaght answer. It has no color marks at all, but does have a sticker with a number on it. I dont have it in front of me right now but I think its ????-123 if that helps. If someone can measure the front and back air hole dimensions with something accurate like dial calipers, that would be a great help too.

I see you have a 73mm and 24lb injectors, so I guess you would know. I'm beginning to think my 24lb tube may actually be a 30 or 36.
I plugged it back in and it runs beastly now. More power and sound than ever before.
