Npp valves not working

KILLA BEE · 08-24-2019, 11:11 AM

Jus got the Borla Atak Axleback installed Npp valves staying open. Anyone had this?

Is your fuse 51 in place?

How do you have your drive modes set? Put all the settings back to Aoto just to be sure. If not that, did you have the NPP settings changed in your tune?

Hmmmmm it's the same in auto. I had the car tuned with str8 piped but when I had the stock Npp put back on it worked fine. But now with the borla its acting up. It could be possibly tune related I guess. I will ask the tuner

Transpose actuators? Springs too tight? Mine were too tight. Borla sent new outside pipes with less spring tension. No questions asked.

Seems I replied to this in another thread. My bad.

The dumb ass muffler shop I noticed didn't hook up the electrical connections. I plugged therm in but the valves only work in auto mode. That might be tune related...
