hello all just finished converting my legacy twin turbo to single so its basically a impreza v3 and its going to get mapped soon

as it stands it has

ej20r (same as ej20k)
vf30 hybrid turbo
yellow 440cc injectors
fmic with hardpipes
stainless exhaust manifold
stainless exhaust up-pipe
stainless decat downpipe
hayward and scott cat back

aiming for 350bhp

would it be wise to change the standard map sensor to a 3 bar, and the current 2 port boost solenoid to 3 port for mapping?
