Change RPM Parameters

[GunRunner]

I have noticed that my 2350 will only rev out to around 1500-1600 RPM's and won't go any higher. If I want to make it to where my RPM's will go up to 2100, is there a change in parameters for that in Isnite? I've also noticed that 70 is my max speed, so if I change my max speed to say 80 will that also allow me to rev out more? I just didn't know if changing the speed would fix it all or if I needed to adjust my RPM's as well. I normally run light and 65 for fuel economy and just noticed today that I couldn't go over 70
