Recently bought a 5.0SC l494 to replace my l320 tdv8, it’s great in most respects, apart from the delay pulling away when not in sport mode. Pulling onto roundabouts and out of junctions has a massive pause between pressing the pedal and anything starting to happen. I end up stomping the pedal because nothing is happening and then it dumps all 500bhp and rockets away.

I’m fairly sure the box is in ok condition, I recently had it flushed and filter changed and the fluid wasn’t black or shiny, wondering if this is something that can be fixed with a transmission remap?[/i]

Can't really say on a L494, but when I bought my L320 5.0L s/c many years ago it did take me while to get used to throttle response, after being used to a oil burner (TDV8) and having to give the pedal a reasonable push to respond, driving the s/c the same it took of like a rocket with the front passenger nearly ending up in the rear seat, so had to learn to be a little more easy with the pedal, however if I was a bit to cautious it could give the feel of a delay when pulling away, used to it now after all this time so it's no issue, probably not your issue just my own personal experience when first having the car, a throttle response delay is certainly something the 5.0L does not suffer from normally unless there is a fault of some kind.

As you have had a transmission flush on it, you could have the adaptive values reset and see how you get on.

I had a similar problem and although this didn't fix it completely, it helped improve it.
