Got a problem with my car (2003 sti) if i go around a tight corner/roundabout quick then when i exit and straighten up (on full power), the boost just totally cuts off for about 2 seconds, missfires a bit with a few pops n bangs then will go back up to full boost again and runs fine!

Any ideas what it could be?

Its not a fuel cut because it did it last night with nearly 3/4 tank!

Its pretty violent when it does it because its as though the engine stops dead for a few seconds

Thanks Ian

 

same problem with mine but i think this has to do with a remap of ecu and using aftermarket boost control solenoids

 

Its called fuel starvation great thread on it from yesterday either on here or in general
