We have 10 degree F weather here and for some reason the boost onmy WRX is lower ??? (on my previous turbo car it would go higher in cold weather)
I'm running the same stage 1 91 Low wastegate as before, did a reflash, put on a normal wastegate map, atill the same..
all of them gave me a lower boost setpoint of around 10 psi instead of the rock solid 13.1 psi i would see on it during summer..
what gives ?
