Not had it before, but on two occasions in two days earlier this week, not long after my fuel light had come on, after a little bit of 'roundabout action', upon hitting WOT off said roundabouts, I got what I thought could have been fuel cut! It was a brief stutter, like the power was turned off for about half a second. And fine thereafter.
Mine is presently unmodified and makes steady boost of about 8-9psi, and the weather at the time was, well, average!
So I'm guessing it's not fuel cut (have never experienced it before to be sure), so I assume I got some momentary starvation due to fuel sloshing to one side of the tank and therefore away from the fuel pick-up.
The surprising thing is that when I filled up about 10 miles later, I only put in 54 litres to the top, and there have been several occasions where I have put in around 58, but not previously had this happen! Also, on the second occasion of the two incidents, it wasn't until about half a mile up the bypass when I hit WOT and got the symptoms. Could the air bubble have taken that long to get through the fuel lines?!
Tried recreating it since refuelling, to no avail, but much fun, hence I now need another trip to the petrol station!
Any thoughts? Comments along the lines of "I would never let my fuel level get that low" will however be greeted with much pannage ...
