RE: 2006 3.9l mods?
Yeah, having this engine is really frustrating. It has a lot of potential, but everyone focused on the 5.3 SS. I have done pretty much everything I could that wasn't custom(intake, cat-back, springs, brakes, sway bars, and I've just started playing with HPTuners so I'm not sure what to expect from that). The next step is a custom cam grind and custom headers. I don't know what kind of budget you're on, but everything for this car is expensive for no real reason. The cat-back from Magnaflow is $700, more than they charge for their Z06 exhausts!

I was just looking at a '08 Impala tune file not long ago. Looks like these engines have some pretty tiny injectors in them. I don't have any datalogs from one, but I would guess that just the basic mods (intake/cat-back etc.) would max out the injectors.
Looks like larger injectors or higher fuel pressures would likely be necc. to go much beyond basic bolt ons.
