Avs2 650 tuning on a 340

I am using 2 blue springs in the distributor. Fuel filter is clean. I checked. Issue is not when shifting but at a steady increase in acceleration. I can see the pump shot richen the mixer based on my af gauge. I believe it's not that
It happens when you have a steady increase in acceleration before the power mode kicks in, it will start to lean out. Which I assume might be normal but it leans out to much.
Yes I have used orange spring. Pink spring and silver spring. Orange does work the best at idle but the power mode does not come in fast enough before it gets to lean.
Total timing comes in around 3000 rpm
