I do not see that RJC has a powerplate for the GN1 plenun with 72mm TB. Is one needed at all or any gains / benefit and which would you use?
I have used the stock plenum with a powerplate and JayJackson TB mod for years and seemed to resolve the back cylinders running lean and making the plugs white, but I have out grown that setup now...any worries with the GN1 without a plate?
Thanks
