Motor in my Supercharged 09 Taco is Chirping

Crankshaft bolt needs to be at the spec, because gear that drives the oil pump is sandwiched. It does not have the "key" to attach to crankshaft. So crank bolt holds that gear with pressure. Its been like that since FZJ80 engines. Which many had faliled because people were removing crank bolt to replace front seal or oil pump seal but did not bother getting proper pulley hold tool so they could not get crank bolt to spec.
Oil pump gear would slip and would not give enough oil pressure.
Also when your pickup line gets clogged it creates so much vacum that oil pump gear may slip.
Crank bolt on V6 engine is listed at 184 ft/lb (compare that to 325 ft/lb on FZJ80 engine )
