Nice informative website, nice tune.
How much different does the car feel after tuning??
Did you alter the timing at all, or just the fuelling.
Happy its all worked out after the problems you initially had.

The car feels amazing. At the top, the hp goes up and up, which is a different feeling compared to what it was like before the tune. Overall, it feels stronger and smoother through the entire RPM range.
I slightly decreased the amount of timing retard - no signs of knock.

I have a question about the Vortech FMU. How does it raise fuel pressure? I remember in my Honda it intercepted the return line and by keep the fuel from going back to the tank, it raised fuel pressure. So how would it do this on a returnless Z?

It has a mechanical FMU that raises fuel pressure to the stock injectors, which is is boost dependant, and a splitsecond box that turns on an aux fuel pump based on boost as well.
