tunning an 03 es
 

i have an 03 galant es (4cyl) i just bought a short ram intake, and im thinking about adding a few more things, no turbo or anything, but header, exhaust and maybe a piggyback ecu

my question is has anyone done these mods and what kind of increase did they see in power mostly the intake because it is gonna get here soon but i never could find any answer as to how it would do on a galant?
