I have a turbo xs mbc on my evo and have it set to 1.3 bar or 18psi (whatever). Well recently I noticed that in first gear, it runs 1.3 fine, but in every other gear, it is running 1.5 and above. I don't know why this is happening and I don't know if it's the weather like someone told me or what. Also I bought the car with the mbc on the car already and I'm not sure which way's up or down. Is this normal and I should just turn it down or is it something else that's wrong. The only other mods I have is the bushur turboback with testpipe and buschur cone replacement filter. Any help would be appreciated.
