ok i was with my friend a few days ago and i wanted to show off with my car, so we were in the 40mph zone and as soon as i got to the 55mph zone i dropped it and 3rd and floored it, after about a second or 2 it like sputtered/ chugged ummm almost violently and obviosly i had no power, so i shifted into 4th and i got to 16psi or so and i was fine, same thing in 5th. then last night, i was comming up a hill and my turn was on the left, i slowed down to 20mph and dropped it into 2nd and floored it , again just having fun, but it did the same thing and its really starting to worry me now.

 

Sounds like fuel cut to me.

 

ok that makes sense, i dont know why, but when ever i floor it, my boost spikes to 20psi then drops down to the 15-17psi range

 

cuz your boost controller is set to high

 

ok
