so i have a 93 turbo 93 legacy wagon 2.2 just got the car a few days ago when i got it from the guy he said that some time it runs at 5psi Boost and then tells me that after i run some of the Summer fuel for a while it will jump back up to 10 psi Boost.... well i filed up my tank once and it has ran 5 psi and then for a hole day around 3/4 of a tank it runs at 10psi which was super cool loved it then the next day 5psi sooooo any ideas on what i have here any how to fix it and i also would like to know how much boost can the car take if its stock? Thanks any help would be great
