Had my 3.6 C4 dynoed today

I've been running a Fabspeed CAI with a BMC drop in filter along with a Softronic flash. I'm having NHP high flow cats installed on Monday and figured I'd get a pseudo baseline. I had 3 pulls on a Mustang dyno and had them run the last pull up to 7100 rpm. I probably could have had them go a little higher, but I'll wait for you kind folks to chime in. I'll be gettng the graphs on Monday, but here is a picture of my last run.

Congrats, that is really strong for a Mustang dyno. You're around the x51 kit territory.

Don't bother taking it over 7k as you're not going to develop any more power but you risk stressing the valve train.

I would be interested to see what the cats can do as I think that's the main bottleneck.

Make sure you give ample time for your ecu to adapt to the new mod before heading back to the dyno.

Thank alpine! Yeah, I'm pretty happy with the results.

Thanks for the info about how far to take it up in the rev band.

I'm looking forward to seeing what the high flow cats do for it. I'm going to give it plenty of time to adapt before going back on the dyno.

I'm going to post the graphs from this past weekend when I get them.

Surprised at the A/F when I got my Cayman dynoed is was pretty much right on 13:1 the whole time.

As I stated in RL, you seem to be on the rich side. I would send in your afr's to Softronic after you install the 200 cell cats and do a other dyno run. They should be able to further refine your map. For the NA M96 motor, you should be between 13-13.5:1 ratio. If you can manage to get closer to 13.5, I'm willing to bet you'll pickup at least 5whp more in various places in the rpm range.
