Npp exhaust valves!
Is there a way in HPtuners to close the npp exhaust valves on start up if the exhaust is in tour mode? I'm tuning out cold start already, but would like the exhaust valves to close as soon as the car starts.

There is a good thread on HP Tuners Forum that covers this topic.

Parish made a post on gere on changing a setting for heating the cats. I dont have any cats so no need for the ridiculous cold start. Of i can get the valves to close at start up also, I can back my car into my garage and not rattle the house every morning. New baby in the house and i dont want to terrify her.

Yes it's catalyst under the general tab. Set the max to 284 and the min to -40 and the engine doesn't start up like it's on steroids when cold.

I'm going to talk to my tuner about this when it goes in for it's tune next week. I have no cats with headers, full exhaust and a cam and that cold start thing is LOUD and I am sure my neighbors hate Camaros now.
