That’s a strategy if you plan to never descend to sea level. Standard air pressure at 8000 feet is about 4 psi less than sea level, so to get sea level max boost up there you’d have to spool the charger 60% or more over stock- assuming baseline boost was 6psi.Good point. He swapped down to a smaller pulley to drive it harder in an attempt to get the same boost as others get at sea level.The TRD blower is a Magnuson TVS1900 which would pair fine with those injectors. He has a smaller pulley to spin the blower harder which is why the OEM injectors are too small.
