99 BEGi S4
This is a 99 10AE equipped with a standard BEGi S4 and Xede. Xede is at default, out of the box settings. IE, super rich (10:1 going to 9.x:1) and super weak timing. Stock midpipe/cat, Racing Beat axle back.
Running wastegate only, no boost controller of any sort, appx 11.5 psi. Pulls taken on a mustang dyno and results are not corrected.
For comparison, other cars that ran today
-96 N/A, 80whp
-1.6 M45 car, 120whp.
-99 MP62, 140whp
-94 FM2L 2560, 170whp
-02 FM2H 2560, 170whp
So I'm pretty happy.
Glowing manifold pictures and video coming soon.

i wouldn't run that car in that configuration long. besides melting **** in the engine bay, that heat is building up because there's a problem (clog?) downstream. there's free power in that bitch somewhere!

yeah it appears that their numbers would compare with a dynojet better if you add 20%. so ben's 192 is really more like 230ish.
and another thought on my comment on the glowing mani... it may not be clogged exhaust so much as just the untuned xede. not enough advance or fuel or who knows.

Here is the timing map as provided by BEGi:
This is the actual timing map I run. It's the same in boost, but I have changed all of what I perceive to be vac cells to 0. This eliminated the highly annoying P0300 that would trigger over and over as I would drive.
I wish I had a table with the stock timing map so that I could see actual timing values instead of offset. I also wish I could corelate the y axis airflow values to actual MAP values. To atleast get me started.
This is the fuel map that came from BEGi and has not been touched by me. It's fat everywhere, and richer than 10:1 up top.
Less restrictive exhaust and better ignition are coming, followed by tuning. And perhaps an ECU swap to adaptronic if it's deemed viable.

The dyno operator told us to expect low numbers. He said that their dyno reads low, even as far as mustang standards go.
Ultimate numbers aren't hugely important though.

started tweaking a little. went back to Bell's base timing map and added just a little in boost. pulled some fuel at idle and in boost. made all the difference in the world.
*assuming that Y value 30 is 100kpa.

With most ferrous metals involved with cars, cherry red is somewhere around 1100F. The EGT is seldom below that when under boost or cruising hard. If that manifold wasn't glowing cherry red, something is bad wrong. It doesn't hurt anything and all nearby components are quite well protected.
