I saw a dyno test of these somewhere... The turbo is already out of breath before 5k rpm. It's a fast-response, daily-driver tiny turbo. A bigger turbo, a couple flow mods, and a tune would net 400+ easy.
Here it is.
But why are we back to the late 80's TPI 4500 RPM days? ****'s dumb if you ask me. LNF was fine, why change it? It can't possibly be cost effective to develop 4 new ecotec variants instead of modifying the current ones to meet CAFE standards... Oh, GM.

Yes, it's a small turbo that is tuned to run on 91 octane. It is tuned for most Buick drivers out there, the mainstream people. IIRC that turbo is only good until around 4200 or so.
Now, upgrades as mentioned above would def. help it breath. Then dyno tune it and go out and have fun. Heck, maybe someone will develop a twin-turbo setup for it
