Depends on the cam specs and how much you do the headwork.

the cams that can use the standard springs can use the standard computer, recommend using a piggyback with the cams that need stronger valve springs to get the timing and fuel slightly finer tuned than the standard computer would do.

Hey Lex, can the 1UZ be successfully tuned with an Apexi S-AFC II ? I have a killer deal on one right now and need to make sure it will work.
