Jeff,
I think it's a great combination. I love my six speed though it took some time to get used to it. The engine rocks! If you are going to bomb, it will respond better to larger injectors than it will to a fueling box. The ETC is the reverse of this. I gather this has to do with the ECM programs being different mostly.
Lift pumps are lift pumps. Some people have problems with them and others do not. If you talk to the dealer, they don't seem to know anything about it. Big surprise... A fuel gauge is a really good idea, then you know what it's doing. You should have EGT and boost gauges as well, anyway. If you find yours isn't cutting the mustard, there's always the alternative of installing a pusher pump back by the tank.
For an engine that will go 400k miles, this is minor.
