PEAKS: 376.1 whp & 324.4 ft-lbs.
Average power from 4500-6500 RPM: 330 whp.

 

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.

 

Did you do that last dyno on the mustang Dyno again ? Where in the rpm range did you retard the timing ? I got very simular hp # and have not touched the timing yet . I was planning to go back and tune a little more [ timing ] but I think I will wait till I put in the torque converter in .I only have Dynoed the car on a Mustang..[no other around ].. We played with the fuel map and the last pull...with a hot car and 84 degrees in the shop...I got 338 whp ....we added between 11 and 12 % to get a idea what it would come out on a DynoJet .And came up with 379whp .He said if I wanted to wait a half hour we could get better # out of it . We had been at it for 4 hours and it was getting expensive .Hope you enjoy the Vortech . It rocks

 

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.

 

Sounds like the fuel pump will raise fuel presurre too high without this and the FMU just restricts the fuel. Got it.
