Installed new injectors and car shuts down after boost

[240sxvaj]

Just installed 450cc injectors i got from deatschwerks car runs a lot better then before. just test it around town running it until it heats up to normal temp and the car doesnt bog like it did before, but when it gets to normal temp and after releasing the gas pedal the rpm drops really low such as to 300rpm and after that it either goes back to normal idle or shutts down on me. When the car cools down it will run good UNTIL it reaches its normal temp. The car idles at a steady rpm and seems like it will idle forever as long as i dont drive it.

already checked for injector leaks and everything looks good plus just replaced coolant temp. sensor. and no vac or boost leaks.
