Right now I'm running about 42 psi static on the return line, have the 1:1 hooked up, 255 walbro and DW 650's for fuel.
Talked to my one buddy today and we think some of the problem might be the direct fit QW intercooler. I definately need to replace it to help with spool also. Full boost comes on around 3400-3500.
I would stop thinking the FMIC is the problem and focus more on the fuel problems. Dont pull more then around 25% you will run into issues with knock for sure then.
