I am shortly to become the proud owner of a g plate 2wd saff cos! With the following engine spec
t3/4 turbo,dark green injectors,3bar map sensor, 4x4 intercooler, bajoo chip, low comp pistons etc

The thing is its been a few years sinse ive had a quick rwd car, an to start with i would like to turn the boost back down whilst im getting use to it!
its running around 25psi at the minuite an id like it down to around 15 to start with! Basicly what is the easyest way to do it? Will i need to by a new set of standard injectors an a 2bar map sensor and a stage 1 chip? or can i just turn it down with some sort of boost controller or bleed valve? or will there be to much fuel at lower boost because of the bigger injectors?
Any advise would be much greatly recived!
