Does anyone else’s overrun turn off?

[DaytonaMatt]

I tend not to drive much in dynamic, but when I do it’s principally for the noise and overrun. But more often than not the overrun stops ‘running’. Does anyone else get that? Almost like it’s dropped out of dynamic although it hasn’t as the throttle response etc are still the same

I noticed this - individual with Engine Noise ON Dynamic seems to do absolutely nothing to valves. In dynamic I think the valves may close if driving on 4 cylinders then re open on a reasonable throttle, I'm not sure on that but either way they become closed I'm sure after a while of slow driving (I've tried to put in to neutral and Rev but there off) guess you can re-toggle or run them open all the time and use the blanks which maybe is the best thing .

Can someone drop the blanks link again please

Isn't this just the result of a hot exhaust?

Not sure on the temp causing it Mike as it seems just to be off, zero noise until you are in gear and give it some .

Thanks Mike I'm going to order some now . Wonder if Stealer will fit when it's in for oil change in March!

My valves are already unplugged. Seems to be if I have hooned it a little it will ‘switch off’ the pops and crackles after a couple of minutes?
