Only issue will be setting the chamber pressures, which is a fine balancing act of the EHA and other sensors. That tool can be purchased for ~$80. I really do not like CIS for its complexity and lackluster power allowed.

I swear I read CIS Flowtech in Alabama has a great reputation for those and they sell them balanced to the EHA.

Do not forget that potentiometer on the side of the flapper body, that carbon strip wears and probably does not help your situation. :/
