Allthough you haven't stated which pump you are running or what size ram, I'd still say you need to do the mods.
Flow = power
Pressure = response
I run a 2.5" ram and Saginaw pump with the WTOR mods, it's a little sluggish at low idle quick manuvering, but it's also a little more stable at speed 50-60 MPH. Sure took some getting used to in the beginning... I'm currently looking at flow (And PSI) control for a solution.
