Ok guys Ive done some searching and found some answers but I still have a question. From what I have found, I can run 440cc injectors and the 272 disc combo I belive it was and 18psi of boost max before I start running into timing problems. So aside from the timing issue above 18psi, why cant I run like 550s or 650s etc to run more boost if I could control the timing. Why does everyone say you cant go bigger with the sfmu. I also have a sfac to help with the tunning. So any help would be great guys and if your gonna say search and read or not give any possitive help please dont bother posting crap that wont help. Thanks in advance to those of you that do help Roy
