If I have a G4 board....should I send to Terry to modify or just sell and buy a "newer" JB4.

Plus, none of the current maps allow boost up to 19.5psi anyways...Map5 targets 16psi max. Does that mean I need to find a tuner to use Map 6 and target what I want? I'm currently FBO and would love to hit another 3.5psi lol
map 5 on the G5 can hit up to 20...I hit 18+ all day long...I am FBO minus meth on stock snails.
