If that helps any, I think in practical terms you won't see a difference as I'm sure you don't plan driving it full tilt balls to da wall. It will still make the power, even the small turbo can do it just with a trade-off being back pressure/heat.

I went to the Holset site, and they don't even have the 561 listed. I know on quick serve it calls for the 551. It just pisses me off that the guy ordering the parts could screw this up. And no, I'm not going to be running her hard, I have her turned back to 485, which is plenty for what I am doing now. Just concerned that if a time comes and I need to turn her back up to 600 will I be doing any harm to the motor? And then I have my mm tune to my cpl. This is not the turbo that as far as I know the cpl calls for. If it will work, and not run rich or lean and can be mapped in properly I will leave it on. If it is going to be a headache, we need the correct Turbo. Need a solid answer, especially in regards to the MM
