I recently did a compression test also numbers were simular but I only had 70 on cylinder 6&8 I had just done the Hughes plenum plate I figured the gasket was gone for a while sucked plenty of oil into the intake, if you read the dodge tsb on the plenum fix they say to run combustion chamber cleaner through it because of the oil build up on valves. The seafoam is basically the same thing I just ran it through mine I picked up 20 psi on 7 of the cylinders and the other cylinder that was a 70 is now 150 seafoam does work
the marvel/water trick works great too and steam cleans everything in minutes.....many use that procedure on the vw forum...

I guess what I'm really saying dont be surprised at all if its almost plugged with the oil soot deposits from runnning it with a blown plenum....if you inspect it and replace it if partially clogged you would see a large improvement in performance..

i did not get into everything i have done recently but i also had to change my cat and o2 sensors, cat was completely shot, i also completely cleaned throttle body and sensors and replaced iac with a new one, did it all at once while i had the plenum off, also did the water pump, t stat and all hoses but that was another issue lol
