Help with fp

I did the fp internals yesterday seem to have no problems. Drove the car home seem to have no problems. Got up this morning and when the car gets to 2000 rpms it looks like the injectors are cutting off but the fuel pressure seems fine and it idles fine. Looking at my dashhawk when it hits 2000 rpm the injector cycle drops to 0 then picks back up and then drops to 0 when it reaches the 200o rpm. My mods are corksport front mount cpe down pipe and corksport exuast and now the cdfp upgrade. Is my problem from the pump or is something else wrong now. Please Help!!!
 
You need to monitor your Fuel Pressure Direct Injection using the DH. You should idle around 390-420PSI and when WOT you should not drop below 1700PSI.

If in fact, if I'm reading your post right, your Fuel Pressure is dropping to zero at 2k RPM's, then you have a bad set of internals.

Also, make sure you plugged in your Fuel Pump. I have seen it happen when after all the lines are hooked up they forget to plug in the pump. The car will still run but like crap :)
 
the fuel pressure is not dropping the injerctors are cutting off at 2000 it reads 420 at idle and rises when i push the gas just the injectors are reading zero at 2000 rpms
