The Repo Depot in South Surrey (King George at Crescent Road) had an E60 M5 a while back, don't know if they do any more but never did look at it as it was an SMG car. What gen you looking at?

yes another FLAT 4 METH ADDICT ,thats it im making t shirts
got thinking after we talked and this is the way i see it , i looked it up on the vp site .m5 is not pure meth it contains more combustion additives and more oxygen .( if i remember its 5% nitro )
the spec grav and reid vapor are higher than pure meth .
so for me if i was switching to m5 from m1/pure meth i would need to jet larger on the main /open up 4-5 thou .
so going the other way without jetting change , your going to run richer .which is ok .how much i cant say .double check with a call to kris.
i dont know if you are running a intercooler or not but reid vapor pressure reminds me of the difference between c16 and q 16 .
c16 being better for hot intake and carbs of a vw due to its lower evap rate and q 16 is better in a intercooler as it evaporates at a way lower temp .
-- also from m1 to m5 pull 1-2 more timing due to the nito
so in theory you could add 1-2 deg which would help with a slightly richer mixture
make sence .
since my daughter has switched over to the "EH TEAM" you know your welcome to my meth , come and get it .
also you may want to ask kris to remap for pure meth as like i said i get a 55 gallon drum cheap
