Not the db2 but the filter head seems to do something but has its limits is what I’ve heardThe DB2 is not self-regulating, if you feed it too much PSI it is forced to accept it and that changes the timing. Just FYI. I've actually heard of quite a few people running Holley Red unregulated and liking it. Seems like it's not too much for the return system but I see what you're saying.
