Hey guys i just bought a new 2009 wrx and its stock except it has spt exhaust and a spt boost gauge. The most ive hit on the boost gauge is 17psi just for a sec and will plateau at 10 psi..Are these numbers correct? everywhere i read and it seems everyone else is around 12 psi..Ive dont many runs and its always 10 psi. any help would be great. oh yeah sorry lol doesnt 17 psi seem hi even though its only for a sec? thanks again
Anything higher than that and your car may turn into the out of control commuter bus in the movie Speed when it hit 50 mph or the time machine DeLorean in the Back to the Future movies when it hit 85 mph.
In all seriousness though, engine management is a good idea to keep your boost in check.
