New LIM job and engine keeps choking on acceleration :(

So I did a new LIM job on a 98 GTP with new vacuum lines and for some reason the car seems to choke on hard acceleration. The car seems to idle great and on acceleration it does great also but as soon as you step on the gas it starts to choke and wants to die. It seems that its running to rich. Car has no cat and it does have new fuel filter, plugs , wires, and before the LIM job it was running just fine. I'm stumped and need some help.
 




Ok So I still need help with this problem, the car bogs on boost put it accelerates normally if not on boost any ideas? Has new plugs , wires, and I checked all the vac lines

I wonder if the MAF sensor could be at fault, or perhaps the map.

I cleaned the MAF sensor , but I still undecided whether thats at fault or not , thinking of replacing. I read the MAP sensor when its bad the engine will run on idle which in this case the car runs fine on idle.
 
There are 2 MAP sensors, one is open to atmosphere and one is connected to vacuum... would mixing those up screw up how the motor reacts to boost?

I thought even the 04+ used the MAP as a baro instead of a dedicated baro. I know for sure the 97-03 have one MAP which is used for both.

Since no one said it, are you sure none of the plugs cracked?
