well i was on my way to nelsons when i discovered a problem. no top end. got to checking and found my mass air sensor only going to 14.4. it should go to at least 28 to 42. well we put in a granatelli. it does affect timing and fuel. and i believe it is himndering me greatly.going to put on another Z06 mass air and retune. just thought oi would share that with everyone
