Yeah there's something wrong with this site where you can't enlarge thumbnail attachments.
As for the improvements. Well the larger turbo is responsible for the added power.
The increased power band I think is a few things. I think first is the vvti, that is known to make a big difference, the number 500rpm is thrown around a bit and that's nearly exactly what the chart is showing. I think that is 90% responsible for it. Also the fact that this turbo is newer tech. When I bought it from Geoff at FR he said that it should spool similar as my old smaller turbo, even tho it's larger, and that is due to the better design of the SX-E. So that allowed for more power without sacraficing response. Lastly I'd say the head-work. The pocket port and cams I think make this new head flow much better, and that's why the car makes good power at similar boost levels as last year. Also the Manley springs/retainers allows for 8k redline where as the old setup I didn't feel comfortable over 7500.
