I drove at Barbs the other night and was experiencing what I thought might be fuel surge as I went over the top of the big hill. Both times it happened as I coming on to boost in fifth gear. The car would stutter and shudder then come good further down the hill??
At first I thought it might be boost cut but it happened in the same spot twice over two laps.

Is this a place where you might typically experience fuel surge? I had just under had a tank on board when it happened.

Even running much lower fuel levels than this at the RAC I have never had this issue before and yes it was my first time there at Barbs, so my bad if it was surge.

Car is a 2010 STi.

Cheers.
