Our CCM also control exhaust valves and the magnetic ride if I recall....So that's why it's no longer called FPCM since it controlling more that just the fuel pump.

This is intriguing. It would be nice if we had some control via the CCM module that would be similar to a Boost-a-pump setup.
I will comment also that that local tuners and I have talked about tuning my E-Force in the future and they state that they can tickle the LT1 fuel system to handle power levels up to roughly 620 rwhp without any mechanical upgrades. When I press them, they just smile and state that its one of their trade secrets. They will even warranty their work. (They have done dozens of corvette LT1s already and are now offer an FBO kit through the local Chevy dealer with full factory warranty, so one has to assume they know what they are doing.)
My only guess is that they are going beyond the typical HP Tuners tuning capabilities and manipulating the firmware directly(?) Are they possibly managing the HPFP via firmware changes to achieve this? This is way out of my league here, but I am interested in hearing from others on this.
