With the intro of FI and totally separate intake paths, that potato sound is lost unless you're running some wild engine mods (cams with alot of overlap, etc). The old carb/intake manifolds caused a lot of weird air/gas flow pulses (read inefficient) thru the intake path to combustion chamber. A lower idle RPM and those inefficiencies caused the famous lope at idle.
I first noticed the lose of the sound on my 1996 FLTRI EVO that came with factory FI. I really missed the sound but liked the easier starting, no more fouled plugs, better MPG, etc that FI brought.
But I thought by now some ultra-smart EFI tuner guys would have figured out how to re-create that sound at idle, without losing the efficiencies gained at all other off-idle RPMs. Something like the high-temp/parade mode, but a mode that mimic-ed the old lope. If someone came out with that mod he'd made lotsa money!
