Out of curiosity. Are there any known FGT mods easily done by owners (to pick up the groceries more quickly

) ?
Short throw shifter is a piece of cake.
If you have advanced mechanical skills, lots of patience and tools, including a press, you could do the pulley swap. You have to remove the supercharger, being extremely careful to not drop the belt, and not bend the fragile metal gasket, but the pulley replacement requires you to remove the "snout" and press the old pulley off and push on the new one. It may or may not involve swapping an idler pulley too.
Replacing the muffler will add some sound. Lots of choices here, use search. Not too hard but some instructions say to remove the clamshell which I did but there is another way, again, use search.
