Ok so there were no vac leaks. Still need to get a boost leak test done. My friend couldn't find any leaks.

He thinks it could be the tranny mount that is cause the stalling feeling.

Any advice?

 

Maybe not a transmission mount but motor mounts. They are fluid filled so if you see them leaking purple stuff chances are they are bad.

Motor mounts that are bad can make it feel like it's stalling?!

 

limp mode is the car thinking something is wrong and cutting engine power to a lower level in order no to damage any parts. IF your car is studdering u could try to unplug your maf and see if that studder goes away. IF it does that might be your problem.
