allright, just wanted to settle this proper size of injector thing real quick

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?

The stock injectors tend to go static around 6200 rpm at 16-17psi depending on the rest of the fuel injection health. (change your fuel filter at the least).
You can run more boost with the 30# injectors. The chip for the 30# is different than the stock injectors..
regardless if you plan to be running such hardcore boost 18-20psi, we strongly recommend you get it on a dyno before beating it up too much. There are just too many variances in an older motor that can cause unpredictable results. Its alot cheaper to make a few runs than to rebuild
