how do you mean missing?

if you mean backing off then your hitting boost cut so upping boost will only make it worse

It sounds as though whoever did the conversion has not removed the auto box control unit up behind the speedo. It is a common mistake.

There is an ECU purely for the auto transmission. Just disconnect it from the main harness and then usually all is well. Unless of course the car actually has a fault.

Do that first and then tell us how you get on.
