:Did you buy stuff through his online store? I have always heard not to buy parts directly from him but rather Z1 or CZP, whoever has the items in stock. I only had to contact him for accessing my tune using his Zemulator and he responded to that. As far as I know he did deliver on the intake manifolds but it took forever. I'm not convinced he's a scammer but definitely a terrible business owner. Good luck in getting your money or parts
Sadly, they've also stopped carrying his stuff. I talked to Nick about it a while ago and he said it's too hard to get inventory from him. Ash makes good stuff, but really, really needs someone else to handle manufacturing while he does R&D.
