1. Fuel pressure low at the rail
2. Dirty injectors
3. Stop using methanol and get back on race gas!

What turbo, how much current power?

How are your dual pumps constructed/setup? Two in a surge? Two in a hanger? what is controlling them?

Are you seeing any spike in fp when the second pump turns on to verify it is working? Also are you seeing any drop in pressure at higher rpm? What is you base fp?
