Stu,Today I fitted the valve delete plugs and with the exhaust valves constantly open it makes no difference to the start up ticking. I still have to put it into dynamic to make it stop.
What I can say is it makes a mega difference to the sound and gives that great 5 pot grunt all the time. I have the FL with the sports exhaust and it has transformed the sound. I am more than happy to have this sound all the time instead of only over 3000 rpm which was pitiful.
Did U notice the car feeling lazy at low rpm with the exhaust valves unplugged?
I did this on my PFL and it left lousy lower in the rpm range. Put them back on and everything was sorted.
A few have reported the lag almost like it needs some back pressure for those slow speeds.
Also any link to the exhaust delete plugs please mate?
Cheers
