I would be very cautious to put a no name turbo on my car as well and definitely no Chinese crap so I stayed away from VTT. Did not like Vargas reviews from BMW world or his condescending approach to prospective customers. I'm picky and basically have my mind set but like to stay on top of new releases, read the feedback and so on. I do know a couple people that have had issues with their Boss kits. I am glad yours has been solid so far.
I was waiting for an answer on this too, so to paraphrase, because CTS has questionable quality products across their line, you'd personally stay away from the brand. Completely understandable.
However I'd also say that being the only bolt on Garrett turbo that uses the OEM style downpipe/intake/DV/WG, etc. etc. it's got some value and might be worth some hassle. That perspective is tough to disagree on, right?
I 100% agree on not wanting to just put any ol' thing on my car. VTT/Vargas was a dick on his thread and I noped out, couldn't pay me to run his turbo even if rainbows shot out my exhaust.
I'm watching this thread though, because the value and performance proposition is very strong with this one.
