Your injectors may be bad... Maybe even taking them out and cleaning them might help.

 

where can most leaks be found..piping?....intake?

 

You'll have to do a boost leak check to find them bud. Yes, the intercooler piping are where they are usually found but there not commonly found on any particular bend. The throttle body, intake manifold, fuel injectors, and even the PCV can be leaking too.
