Default Should I run a 2 Bar or a 3 bar Map sensor in new setup?
01 ls1 took a dump. Building a 383 stroker, tc78rear mount, going to run 8-12 on street, and on high 14-16lbs. What map sensor is approriate a 2 or 3 bar? And do they need the harness adapters? Heres the ones Im looking at.

PN# 12223861 3bar MAP
PN# 16040609 2bar MAP
