Cable: Less electronics.. adjust idle with a tool.. can flip the butterfly with your finger to show off to friends. Down: have to run a cable at the right angle, have to punch it though the firewall, less adjustability, subject to mechanical failure. Oh, with cable you can go with a bigger TB.. like 105mm.
TBW: cleaner install, more adjustability, easy to wire in gas pedal, cleaner firewall, comes with GMPP harness kit, TBW TB ships with all new GMPP crate engines. Down: subject to electrical failure, stuck with 90mm TB, can't blip the throttle from the engine bay so you have non-impressed friends.
I personally love the TBW system on Penny.. many hard miles with no issues.. after all, this stuff comes on new cars so it's pretty dependable (just stay clear of the Toyota TBW stuff)
