I don't have any experience with under the carb throttle stops but I do have some experience with using an in line throttle stop with different ron's fuel injection systems (both toilets and terminators) The first problem is that you need a ridged pedal stop if the pedal moves it will not be consistent and second if you use a pinch valve to slow the opening rate don't slow it down to more than .6 seconds (stroke time) as it will not stroke consistently if you do.
One more thing if you get with in .01-.02 of the index then consider using a little ballast to fine tune that last .01 but pay attention to where you place the ballast as ballast on the front will have a different effect on et's and possibly reaction times than ballast located in the center or the rear.

Hope this helps.
