Borla Npp valves wont close
Has anyone on here gotten there car hp tuned with the stock Npp then installed an after market Npp and It didn't cooperate. Did you have to change the Npp settings.

Transpose the NPP actuators when put Borla on? That's one thing to check. My springs were wicked tight and wouldn't close. Borla sent me new ones with less spring tightness. Work fine. Hope this helps you sir.
I'm not HP tuned, however.
