Has anybody installed the FASS sysytem on the 05 610 yet? If so how does it perform?

i was told that it is kinda pointless on the new common rail trucks as its ALOT better then previous......unless u are gonna be running higher HP like 600+

It seems that I read elsewhere that excessive fuel pressure to the CP3 actually chokes it and hinders it's performance. I'm not sure if this was on a stock or bombed truck, correct me if i'm wrong here guys...

I think we need to see what the stock pressures are like on an '05 first, before talking about adding additional/replacement pumps. Anyone got an '05 with a fuel pressure gauge yet?

I was told by F.A.S.S. that the install is causing the pump in the tank to shut down so they are coming up with a way to bypass the in tank pump.This was about 2 weeks ago ,so they might have come up with something now.
