CAT 3116 problem losing power at top end

Hi there,
I have a 3116D and have a strange problem. I recently had the injectors, fuel pump and turbo replaced and since doing this the boat doesn't run properly. When you run the ignition all sounds well, you accelerate and all is well - the problem is that when the turbo has come in if you lower the throttle slightly and then reapply the throttle there is a huge loss of power for around 3 seconds and then all is well again. You can recreate the problem over and over and it seems to get worse the more you do it. It is as if there is no fuel getting to the engine but there seems to be no obvious leak/disruption. Could changing the turbo, injectors and pump have caused this or could it just be coinsidence. Any help greatly received!

if u put an 100-150 ohm resister in the plug that goes to the fuel temp sensor it will help. also the computor sounds like it is programed to a throtle response you dont like. take it to cat dealer and have another throtle program while you rare driving the trk. i think there are 3 choices
