Re: 37xd seems to run rich
A freer flowing exhaust may help counteract that, depending on what exhaust you are running currently.

Re: 37xd seems to run rich
Ooooo ok, check your fuel pump and make sure it is functioning correctly. Also, what size fuel line are you running?

Re: 37xd seems to run rich
i would first do a health check. leaking valves, popped headgasket or a flat cam can all do this. does the oil smell like gas? tanks can swell and shove fuel into engine through vent line on top of hi pressure pump . aside from that its commen these days to have the vent line on the high pressure pump leak fuel into throttle body when the needle dosent seal on the seat. the hi pres pump has a needle and seat just like a carburetor. u can remove the small vent line and install a longer line to exit below the engine. then u can see if and when the pump is flooding itself
