Reason I ask is that I drove Doug Stirlings car on sunday, and I assume its on one of these map sensors as when I changed up a gear, it felt like it went rich for a split second as I put my foot down again in the next gear, there was a noticeable hesitation to it.

Went like fuck other than that though, and very smooth and perfectly well mannered in every other circumstance, but it was quite annoying when it did it.
