3.3 CIS turbo motors were built to supply at its best (special wishes 3.3 S) about 280rwhp/330fwhp.

It requires over 55% more fuel delivery than stock to get to 470fwhp.

By fattening CO I suspect we can stretch the stock fuel system up to about 340rwhp/400fwhp at is best.

After that significantly reducing control pressure can support about another 10%or so more HP.

My 2 cents experience

Use up graded fuel pumps and increase fuel pressure is the easiest way to get more fuel with CIS setup .

Considering the fuel flow capability, the CIS head is not a limit. It can flow huge amount of fuel..... But the stock injectors are the limit and the restriction. By using the injectors of the 3.6T, you can really get a huge amount of fuel. The problem will be to deal with low RPM.
