I will probably leave my 1931250 Greyhound Challenger #3977 synced to the smoke as manufactured, but I reserve the right to change my mind once I see a video of the un-synced Challenger.
Will the new Big Boy have the same synced drivers? I see no mention of alternating smoke puffs. My original Vision Line Big Boys retailed for $2,999.00, significantly more than the newest version being advertised.
Sincerely, John Rowlen
