Default Car would hestiate snd lean out under wot .

Hey guys i need some help here .
I recently replaced the Txs map sensor . Due to vibration snd heat caused the old One to break and the car was acting weird . Now after replacing map sensor the problem is still there. , when i wot the car a/f just leaned out to 16-17 . And it feels like it choking , could this be fuel pump related ? Help would be apriciated .

Ps : posting from my iphone .

Make sure the map sensor is actually working. Hook up your laptop to the UTEC and check the dashboard/logs.

Ok heres th problem . The car runs fine after warming up , af in the 11 under boost but after a few runs the af would lean out as the engine gets hotter . Maybe my 4 years old walboro pump is getting tired. ?
