Hey dude,
By any chance is it dark metallic blue with the darker 03 wrx wheels?
If yes, it's my old car and I had Allstar Garage do the work on it, along with the Verso
ECU reflash and the tune is safe along with the mods with it..
If not the same car then I cant comment
but 20psi is the max I would want to go on a vf34/ej205 combo for safety..
