:-D Mr Jay89, I have some (a little) experience with pulse tubes on my 89 and based on your stats I might be able to help a bit. My tube leading to the cat had been rusted out for a long time, additionally the check valve for that tube was also rusted in two. I replace my cat and muffler(flowmaster) and decided to completely remove that tube and leave the air port capped on the new cat. With this in mind I then capped off both vacuum tubes between the solenoid and the valves. Finally, I taped over the two holes on the stack air cleaner (you have a weber so you can omit). To date no problems and smooth operation. Basically all I have left commected is the tube to the exhaust manifold (since the vacuum line is capped and it has a check valve, it acts like the tube is capped at the manifold. Whew!
For your set up - since you have nuttered and webered it, you have taken the computer out of it. THEREFORE, and here is my hypothsis, you can remove both tubes, checkvalves and vacuum lines and cap all openings (cat, manifold, two vacuum). Basically this is how you are running now but you have a bunch of extra stuff cluttering up your engine compartment. 
I hope this helps OR I hope that someone will let me know if I am WAY off base. Good Luck!
P.S. I'm dying to nutter and weber mine but it currently runs like a champ and I don't have the heart. At the first sight of carb problems - BAM - replacement! :lol: :lol: [addsig]

Jay89, I had my cat removed (nuetered) and a flowmaster installed. Whan I did that I removed the check valves and tubing that went to the exhaust system and pluged everthing on the stock airfilter like Jeepngeo did. Everthing is running great with no problems. [addsig]
