Water injection?  Not sure how the Mac11 will respond
to it, you probably need a timing map that's advanced
a little to take full advantage of it.

I've done it and saw mild gains, just hog out the
veins that are shared, I actually removed the one that
is to the left when you're looking at it.

Try getting that turbo on there, I'm curiouse to see
if you get if you get an increase in HP with the stock
EM on there.  Also maybe think about a cam if you want
higher rpm performance.

I know you don't want to hear this, but the header is
the mother of all upgades, and with the turbo you
have, it could be really fun.
