|Oh you are talking about THESE:
yeah they are so new I doubt anyone has experience w them yet. Id talk to Z1 on the phone and probe em about who has them and how it went etc.
The listing I was looking at was the 525... not the 525+? :
Personally I would not go with them and stick with more trusted JWT / SZ Purchased turbos. I purchased my last set of sport 700s from SZ directly and had zero issues.. minor clocking was required on the RH side.
