I put my car on the Mustang dyno at work tonight. I did one pull with my modified tune in it and one with the stock tune. They made almost exactly the same power. Mine made 400 and the stock tune made 398, both SAE corrected. Uncorrected power was 425 and the correction factor was .940. I'm told our dyno reads on the higher end of Mustang dynos but still lower than a dynojet.

My car is stock other than an upgraded heat exchanger. Charge temps were around 110 degrees on all pulls.

I'm linking the dyno sheet, an HP tuner scan, and a crappy video.

First off, Excellent results!!!

Next have you talked to Zooomer about porting your Supercharger? Also what exchanger did you go with? Was it the Ion you guys sell? I am looking at a Fluidyne or Stillen as we carry both of them.

On to your tune. Did you also change your commanded Stoich or just AFR in PE?

Thanks. The heat exchanger is one of our stage 3 Grand Prix units with different tabs. I mounted it to the underside of the bumper extensions. I can see if I can get you one like mine if you'd like. Just let me know.

I have not discussed porting the supercharger yet but it is on my list. First is a CAI. I'm going to get started on that this week.

I changed my commanded AFR in the PE table to 11.5. The car was quite a bit leaner than commanded on my tune and the stock tune. I noticed this afternoon that the coupler after the MAF was partially disconnected. I'm sure that was the problem.
