You can tell it's a knockoff by the serial number. What kind of mods do you have? Is your manifold, o2 housing ported? Mine didn't get full spool till literally at 3k...should be sooner but I dont think my o2 and manifold is ported. I'm sure once you port the exhaust manifold and o2 housing, the e316g should spool right under the 3k mark.
side note: I remember taking my friends for a drive in my car asking me if it was normal for the turbo to spool that quickly
