I am running what amounts to about B30 (I buy the 100 and add #2) and have noticed increased throttle response and power too. Not much obviously but improved nonetheless. I was on the interstate today and nudged the throttle to get around a slowpoke and she really jumped and ran. The quieter performance sure makes it nice too. I am guessing as it cleans the injectors and lines the improved response is from less restriction in the system. Now that I have a reliable supplier I am going to start running straight bio.
