Explain what you mean. What m/s are you changing ?

 

Every coil will be different. Run too much dwell and you risk damage. So if you do not know how much dwell you should have, it's best to stick with lower numbers. Seems in your case the higher dwell is causing the problem, so if it runs better at 3-3.5, then just leave it there !
