Im looking at buying another eboost street. Im just wondering if anyone has used the rpm switch in the eboost street to change from sp1 to sp2 while on boost? ( using the switch logic function or grounding the green wire) On my last eboost street it wouldnt allow me to change from sp1 to sp2 with the push knob while on boost but fine in vaccum, so I want to make sure I can do it with the wire. Cheers
