Any way to adjust exhaust valve open rpm?

HC700 · 05-12-2021, 02:45 AM

Hi guys,

Anyone know if theres a module or any tune that allows programming of valve operation rpm? Currently have Alpine's tune but Alex was unable to make it work so open to other companies.

I know in efficient the valve opens over 4k rpm

Would like to adjust it to 3k or 2.5k if possible.

I try also to find new controlers able to ajust on angle, not just open and close. I heared new m4 are able to do that.

If you watch the two videos by CaryTheLabelGuy you will see how you can program flap control for your own stock tune.

Exhaust valving is a minor thing that most Bootmod3 tuners don't want to bother with, but will if asked.
