Well, yea ideally I'd have said do the exhaust first, suspension second, then MAF then turbo but I got a helluva deal on this turbo. . . oh wait. . . my "friend" (wink, wink) got a helluva deal on the turbo and he/she ( 
In case the wife is reading this) couldn't pass it up. I figure it should be replaced as part of the pending oil pan gasket replacement since so much crap is getting pulled apart anyway, plus it makes for a nice reward when the job is all done.
Soooooo. . .
Looks like the turbo happens first with Guru 18 psi chips for now and intention of Vitesse chips/MAF/piggyback/Christ-only-knows-what-else later on down the road after I get the 3" SFR exhaust (or equivalent) on.
This 951 is killing my Callaway project - keeps suckin' up all the play money!
I have enough parts to put on though. I don't think I need to spend any more on the Callaway until I deplete the pile of parts and crap I already have for it by actually installing them. I'm telling you - it's a sickness! I need therapy or something! Or something cheaper - like a 911.

And the formula at the top that page is correct and very easy to use if you don't trust the calculator.
BTW, I use Siemens #72 on my car and have not noticed any problems with the idle although I have heard others having problems with identical injectors.

Yes, as I said, the BSFC recommendation may be a little conservative. But it's up to you to decide what value to put in to the calculator and from what I see it calculates the correct answer from the data you provide. And in the end it's a lot better to use a BSFC that's a little to high and end up with injectors that are a bit to big than the other way around.
