I'd definately turn down the boost to about 5-7psi until you have larger injectors and have it tuned properly, not all stock injectors are able to handle the same amount of boost you could have one bad injector and not even know it... playing borderline is not fun nor the ideal way to figure out your limits. It can end up to be a very costly adventure should you lean out too much. IMO save up and get a wideband o2 sensor setup (AEM Uego is good) take it to a dyno and tune it for 5-7psi, then save up for larger injectors.. how are you tuning? what FPR are you using?

What gauges do you have as of right now? I wouldn't even drive my car until I had a/f, oil press and vac/boost at least. Too many things that can go wrong.

Sounds to me as though you are gettin boost happy alittle too soon... could cost you big in the end.
