Can't say my HFS is a BIG improvement over the standard K27. It certainly does have more at the top end but possibly slower spool at the lower range. I have an airfield test day coming up in June, so will post findings afterwards.
With the standard headers and turbo, I noticed I lost power near red line (which is why I installed the HFS) but still managed official 168mph vmax. (My car has been measured with mixtures both before and after so is running fine.) If I can't better that with headers and HFS I'd say that will be conclusive. We'll see...
