Well I am looking for either a gt25r or a gt28r for my car. I was wondering about what rpm most of the stockish msp's reach full boost. What is the stock psi?
I have an external wastegate so if you have either a gt2554r or gt28r that has a bad actuator etc. let me know. I don't need a brand new one, but I need one thats not a pos.
let me know what you have!
