Don't forget to monitor your A/FR. I added a Stillen air box, the A/FR would hit 15:1 just before 3,500 RPM. You could feel the car bof and choke. Then the system uses the closed loop fuel maps and A/FR dropped to 12.5:1. The velocity stack on the Stillen speeds up the air too fast fro the MAP sensor.

I would be interested in helping out with this. I can get you on an AWD Mustang dyno for a $25 strap fee plus $15 per pull, or $85 an hour, whichever is cheaper. We can switch parts between pulls right there on the dyno. I can also bring my camera/tripod to record the pulls if you don't have one. The shop I use with the dyno is over by Keller in Fort Worth, and has no problems doing it at night when its cool.
