Intakes should help throttle response. 3rd gear for me is the most fun to rev match. 2nd and 1st take a second longer on the throttle if at higher speeds. I don't use SRM because well, my Camaro is auto with paddle shifters. To me, that similar enough to SRM rev matching. I like it old school!
But if I am going to the track or corning hard and fast, I will use SRM because while I know how to heel-toe, I am not perfect like SRM is.
