So...
800-4499/4999 = Not in VTEC
4500/5000-Redline = VTEC
What about if your using a different activator without the z6 computer and with a a6 dist. He has some sort of little box with a yellow thing plugged into it and he said he has different ones with different numbers on them. I'm just asking becase his car is barely faster then my stock si even when I drive his and he drives mine.
