This especially on early drive by wire cars they needed that small delay to let the computers determine air / fuel inlet. Years later computers in cars have come a long way but most all drive by wire cars still have delay built into the throttle body. Yes its small maybe one tenth of a second but if it takes one tenth of a second to get to wide open throttle then the car reacts slower. If items like the Sprint booster cut that time and open the throttle blades 8/100's faster then your 0 to 60 time has to improve. Sprint booster almost gives you the 1 to 1 reaction "on the red race 9" setting that carb and throttle cable vehicles had in the past. Just my opinion and I know there is NO Horse Power gain with Sprint booster, that being said throttle response and car reaction is quicker. Today I like it. Maybe next week I won't.
