CAMARO6 - View Single Post - Is there anyway to alter or modify the NPP functionality other than a HP Tune?

I would like to modify or tune how the factory NPP functionality works. More specifically tune Track Mode so the valves stay open 100% of the time except in 6th gear (i would leave as factory defaults).

My car isn't modified enough to justify getting a HP Tune which I know can tune and alter how and when the valves open and close in each drive mode at what rpm. So I'm looking for alternatives. Can the dealer do it? Is there any other systems than can do it?

For those who don't know, No, when the car is in track mode the valves are not open all the time. They are closed below 2,500rpm in gears 2 and 3 and closed below 2,000 in gears 4, 5 and 6 (at least this is how it is in a 2018 ss 1le).

I would like to modify track mode so the valves never close, except in 6th gear. The only way I know how to do this, is with the HP Tuner software.

I also do not want to pull fuse 52 and disable the NPP functionality as I have a Corsa NPP catback and need the use of stealth mode on occasion.

Thanks.
