When my car is on full boost it sometimes dumps it all, even though i have my foot to the floor.usually between 2nd and 3rd gear. Its like hitting a brick wall. It only does it evry so often. Its driving me nuts, any idea's?

 

fuel cut maybe, normally means overboost, airleak, it will feel like a sudden stop

what year and model car is it please

 

Hi bud,

My STI does that as well but i have discovered it only does it when there is less than quarter a tank of petrol.
So mines is an easy fix well....maybe an expensive one
