Forgot to say this only applies to a std actuator. One way or the other, removing the amal valve will leave you with less boost.

Best way to check fueling is to bring it to a tuner... (I sound like one of "them" now)

You can do it yourself if you get yourself a wideband lambda kit. But MFI can be a pain to adjust so better leave it to someone experienced.

Oh and just to clarify that: I'm not knocking tuners here, I just hate it when people jump on the "it'll explode if you don't bring it to a tuner"-bandwagon, even though the technical question asked doesn't require any mapping etc. to be solved...
