So my turbo is on in the next 1-2 weeks, I plan on running 15-17 psi for now. And from what I understand my stock injectors will work fine for this application. Buuuuut, if say I wanted to run 18-20 psi I realise that I'll need to upgrade them. Would my car run fine at 15-17 psi with the larger injectors? Pros, cons, etc.? And also, to the SNS guys, I'll need a chip. Off the bat here I'll be running the stock injectors, when I upgrade them will I need a different chip?
