My theory is that that the S65B40 and MSS60 DME are just very tricky to consistently dyno. I could almost bet that these cars with similar bolt ons, but different brands, will perform very similar in acceleration despite brands and dyno numbers. Just a theory though...
Looking at every 100% stock E9X M3 on the forums, they can vary as wide as 40+whp. I doubt BMW is that inconsistent
