Is the stock regulator on the return style rails on 03 trucks 1:1?
if it has a return system, yes 1:1
Thought 02 was last year for it, but they may have switched in 04...having a brain fart
i have a buddy with a 03 HD and his is return style...
Yeah I thought 03 was the last year. I swapped my 05 returnless rails to factory return style and just wanted to double check. Does anyone know if it has to be connected to manifold pressure after the TB or can I boost it before the TB?
