FMIC Pressure loss question I already started a trouble shooting thread awhile back on my D1sc losing/ not making boost...
I got a lil issue with my FMIC. How much boost, if any, should the FMIC absorb after the intercooler? What i'm thinking is my procharger is making 12.5psi AT the blower and only 6psi AFTER the intercooler. It's a Griffin I/C but are the FMIC's known to absorb some sort of boost?

That's a lot of loss. Maybe there is a leak between where your getting the readings. From what I understand cooler air is more dense and will not read as much boost which would explain a little pressure drop if the FMIC is cooling the air better than the twins. I dropped 3 lbs. doing a Vortech but it probably adds 10' of plumbing (12 to 9). I did get 2 back by switching to a pressure side MAF.
Rule of thumb for a new IC is 1 to 1.5psi of drop at the cfm that you want to move through it. 3.0 psi would be very high. 6psi is off the chart high. Get your core dimensions and go to www.bellintercoolers.com and compare it to their core cfm ratings.
