NPP Exhaust not working??
OK, my NPP is open at idle, closes just off idle but will not open back up under acceleration. I have ran the RPM up to 5K and they flaps still don't open. I did this while in neutral in the garage. Does it have to be in gear and actually moving to operate properly? I've drove it but can't tell if it's opening for sure by sound. ??????

Yes, engine has to be under load for the manifold vacuum to drop and allow it to open.

Fuse pull will keep it open.
