I have a simple noobie question. The only thing I have done so far is the air silencer mod and the 3/16 solinoid vacum conector. Within a week I will have an safc on. In a month I will have a cat back exhaust and I now this is cheap but I will have the up pipe gutted. I have a factory boost guage to monitor boost, but no egt. My question is this, should I put on a dawes devices mbc now? And at what psi should I run it without running it too lean so as to damage anything until I get the up pipe gutted? Or should I just restrict the air to the wastegate for now?
thanks for any opinons
