I liked mine. Basically some people will tell you they have trouble maintaining stoich at high vacuum situations. Like a deep decel or idle for some people they will go rich. Mine did this, but I cant exactly blame the injectors. I dont know if the data was every full correct and I didn't have an adjustable fuel pressure regulator. Still either with, I like the injectors even with them going rich on decel.

We used a vacuum referenced fuel pressure regulator. The Walbro 450 we were using and free flowing fuel system resulted in over 70psi. So in vacuum we cranked the fuel pressure down to 40ish and allowed in to rise a it got into boost. It made the truck much more street able and mild mannered while allowing it enough fuel when on the throttle.
The rich condition on Derek mentioned above was an issue prior to referencing the fuel pressure.
It is likely you had fewer problems due to the more thirsty motor which could eat up the extra fuel more easily.
