I personally went with Berks because of the sheer amount of experience they have with designing and selling HFCs for VQ37HR engines. They initially adjusted the anti-fouler bungs until they hit the lowest rate of CELs which shows in the fact that it is very rare someone would get a CEL from a Berks HFC.
