the boost can be terned up to a safe leavle of the chip if you have not got a clue what the chip is would say get a afr gauge and keep an eye on it.

Find out who's chip it is and they will tell you. Bin the FPR or sell it on as will almost always end in tears

As said need to know what chip maker/writer says with regard to boost, fuel pressure.
The fuel pressure has no doubt been on a std pressure regulator when the chip was written so it needs one of these as if they have different rates on boost off boost it will throw the fuelling out.
At the very least find out whos chip it is and ask, or get it on a rolling road, might save you a engine.
