the BG power enhancer you get off of Ebay is absolutely the best stuff. try it on a beater daily driver you will be impressed, techron is good stuff but not the same level of strength as the BG
Sea Foam does work great, but it cleans the effects of carbon in the engine, a catch can prevents oil from going into the intake. Two completely different scenarios, a catch can is always a good preventative measure.
It will clean the plenum some too if introduced into PCV system no?
I mean it would be literally going right in there,,,,kinda thought that was the whole point.
On other hand carbon coated or not I never ran a catch can on my '04 GTO & it dynoed higher (same mods) @ 115k miles than it did @ 50k miles so while I guess catch can is good "peace of mind" for an OCD freak - my experience is it isn't necessary, the new DI engines though......makes sense to me. I did run lucas fuel system cleaner & seafoam a few times while I owned it.
