If the pump is a constant pressure then they don’t have a leg to stand on concerning the FMIC. We’d need to talk with a BMW mechanic to verify.

HerrK's information supports that the HPFP produces a constant pressure based on RPM. This is critical to Vintage's case because the failure of the pump has nothing to do with how much horsepower the engine is producing.
Therefore, he can say the FMIC did not cause the engine or the HPFP to operate outside it's normal range. The failure of the HPFP is a result of it own poor design
