got a 92 liberty ej20t motor in it with alot of the common mods done to it just wondering whats the max psi i should run from day to day? running 15-16psi can i go higher?
cheer

Woohoo, another legacy GT owner like me... Im slightly less lonely.

13psi is as far as you can go with the standard ECU. Boost Cut kicks in at 13.5psi. Need to put in a one way valve into the MAP sensor for removal of boost cut (bad but easy short cut fix). Better yet, get a VOS Chip put into your ECU. VOS will give you better fuel maps, and boost at 16psi with boost cut raised to 18psi.

In any case... go to www.rslibertyclub.org for the info you could ever want on Libertys and Legacys

go the leggy.
