Fuel problem
 

Ok guys just wondering if anyone has an idea what this could be..
Basically my car under hard cornering at 5800rpm (there abouts) is having what i think is some kind of cut out of fuel.. This happens when i go from a right hand corner then immediaetly in to a left hander:( obviously this is at pace 2nd or 3rd.. this has happend with 3\4,, 1\2,,1\4 of a tank..
This is the only problem i am having with my car, it idles well no over heating or anything like that,, it drives amazing pulls well no straight line splutters just the problem i have mentioned:wonder:
Oh yeah my car is a blob wrx : re-mapped, K&N, decat & back box..:thumb:.
