So I have searched the all over and have not been able to find anything on this, but perhaps its my wording when i search. So occasionally what will happen with my 2015 WRX (Stock) is that I will approach a stop sign or stop light, and when its time for me to accelerate, there is literally no power/acceleration for a few seconds. The vehicle just crawls for a few feet before i have to floor it so the boost kicks in and i can get up to speed. What is this? Why does this happen? It does not happen all the time, it is very sporadic. Just curious.
