So, following some suggestions from people on my previous posts... I checked for boost leaks, and also checked my cat for blockage via the "pull off the blue cap and feel for backpressure deal"
Boost leaks were found at the dipstick and slightly at the oil fill cap. Also somewhat in the middle of the intercooler... a few bent fins... looks like that isn't getting done immediately. other than that, no apparent leaks. Interestingly, the car will run with the oil fill cap off or with the dipstick pulled out... hmm... intercooler leak causing this?
Catalytic converter test yielded these results: decent pressure coming out of sniffer pipe at idle, If given throttle - pressure increases signficantly... to the point that the flesh on the tip of my finger was noticibly being indented. I don't have a gauge to put on it, but I would put it at more than 5 PSI without question with a little bit of gas applied. The car also seems to run a little better with the blue end cap pulled off. Also, there if the cat is shaken you can hear crap clinking around in there.
So, I guess this would probably indicate to me that I need to do the following: Get a new oil fill cap, get a new dipstick, bring the car to the shop and have them put on a new catalytic converter for me, and while I'm at it, perhaps get a bosch 710n BPV because A.) it only can help as my BPV is stock and B.) performance gains will also occur.
Does this sound like a reasonable strategy? Would I just be smarter to have the exhaust people fab up an entire cat back for me? I've got the 20v dual 2 inch exhaust.
