if it runs with a vacuum line popped off, your idle is too rich. That can be from bigger injectors or a different MAF if you have not compensated for it.
DON'T adjust the idle set screw for the throttlebody! All that does is keep the throttle plate from scoring the aluminum housing and creating leaks later on.

If it otherwise runs fine, you may just need to do some easy fine tuning of the MAF with your SAFC.

Why the heck would you need to reduce the spring rate in your wastegate to prevent surging?

Also:

Why wire the fans on...does it run too hot with the extra hardware? Get an SVT radiator, I've never had an issue with mine.
You can use zip ties to keep your vacuum lines on, or hose clamps but zip ties are cheaper, easier and can be black so they match the hose.
