I found just the opposite. A normal pump is light ALL the time like any older GM, where the EVO is heavy at highway speeds. I can steer GMs without EVO with 1 finger.
Interesting.
Well, I should perhaps give my point of reference.
I had the EVO on my 1998 Suburban.
I removed the EVO and installed the GM-sanctioned "kit" as a replacement for the EVO, consisting of a fixed flow control orifice (not valve) to replace the EVO, and a length of pipe, i.e.,

After installation, the result was an average (not light, not heavy) steering feel regardless of vehicle speed.
The resulting flow rate for that flow control orifice, I do not know. The steering feel would depend on that flow.
Since I don't know what flow control orifice might be provided in the replacement pump (OP's situation), I should probably not speculate on the resulting "feel".
