im gonna be running a t3 garrett with internal wastegate, uberdata, intercooler, with 8 psi, can i just use 370cc if im not gonna wanna turn up the boost, just if i wanna stay at 8psi, is 370cc ok?

 

also, should i go with high impantenace, or low,

 

First off, what motor?

Second, you are probably going to have to turn up your base fuel pressure as you will be near max duty cycle on those 370s.

Third, it doesnt matter whether they are saturated or Peak 'n Hold
