Mine hadn't, till today lol.

And aye mate, there was nothing over 3k, it just made noise and went nowhere, I knew the feeling, one of my mk2's was the same, till you fixed the IMRC on that Aswel lol. There rebound for it, just a bad design from ford, well, bad placement, bolting it to the top of a red hot cam cover isn't there pinnacle of design is it. Thing is, a lot of people don't even know there not working, because the don't throw the EML when there not working like ST170's do, if you didn't know there meant to really pick up at 3k revs, you wouldn't have any idea anything was wrong
