code po234

Truck was really beginning to start hard 4-5-6 cranks. Fuel pressure was down, so wwnt out and replaced the lift pump.
Started right away for about 30-60 starts. Now it is back to 6-7-8 cranks and spit out po0234 ( turbo boost limit exceeded). I feel like every start is going to be its last one. How to Fix?
map sensor? What where how?
