I've a couple of fueling problems that I'm trying to sort. Can anyone give me some advice?

1. When driving through the gears fairly hard (say70%), the A/F ratio flicks to lean for a couple of seconds as i change up through the gears. This makes the engine jump on it mounts for a moment. If i keep my foot down the A/F return to a rich condition and it accelerates away.

This does'nt seem to happen if I redline throught the gears or if I drive it with slow throttle input between gears.

2. If I drive at a constant rate on the motorway with full boost (10psi). After about 1/2 a mile the A/F starts to go lean and the engine jumps on the mounts.

I am running with a Avonbar hi boost needle and I have checked the fuel regulator (set at 4psi and increases with boost)
