just been out in ZED and was going on to an A road so put my foot down in 3rd, and noticed alot of 5iht out the back get in to 4th and it was like being in safty boost (but boost was fine). Anyway doinf 70mph in mid lane (5th gear) go to over take a van, so build up speed gently boost went to 0, and the car stat's to shack so i stay behind van came of the power and it still does. (at 1st i was thinking that a tyre had gone). the car idel's like it's only on 4 or 5 but has no loss of rev's, but under load it's like going on and off the power.
