ECU and Tubo options

[flametail]

I haven't seen anything about this so I figure the ECU doesn't have to be adapted or tweaked if you add a larger turbo...but, if i decide to upgrade the turbo, what kind should I get? I don't plan on making an obsurd amount of HP and I would rather it be kinda inexpensive (not cheap). What numbers would I be seeing with different turbos and what are the pros/cons of the different turbos?
