There are a few back to back test graphs available from different manufactures.
However on an RR day mine made 141 HP along with another guy who had almost an identical spec (think he had a pred, mines oem ecu) he made 141 too.
Guy with 708's on a standard rev limiter made 146ish
So technically he had worse cams and wasn't even hitting peak power but still made more than any other
