With EFI live you can control everything the turbo can do, the LLY uses a Variable Vane Turbo, or VVT, or VGT, or VNT...... in essence, on the drive(exhaust) side of the turbo instead of a set of fixed vanes that require a set amount of exhaust pressure to drive the turbo, a VGT uses a set of variable vanes that can allow the turbo to spool on very little pressure, makes for a very little turbo lag, they also do not require a waste-gate because when the turbo is making high boost, and you let off the throttle the vanes will open allowing all the boost to flow out the exhaust instead of over speeding the turbo, it creates a loud "wooshing" sound that can be a bit off putting the first time you hear it
EFI is the end all-be-all tuning for the Duramax, i suggest downloading the program off of EFI's site and play around with it, you can down load it free without the V2 flashscan, but you cant save changes to tunes, but you can get a feel for how complicated it is with fueling tables, boost tables, injection tables etc...
a PPE or suncoast transmission would be under extreme advisement, if you add more that 80-100hp you can expect to limp your transmission in a hurry
