anyone ever put a throttle body spacer on? Did it help , or are they pointless??

If you port it, I would say you would need a spacer or it will flow less air at WOT. I say this because the machined in ramps actually guide airflow over the humps in the intake and people here have verified a ported throttle body with no spacer actually loses between 5-15 RWHP.
