Did a dyno run this morning
<img src="http://tomasz.data2net.org/gallery-albums/album08/dyno.jpg">
Did 3 runs, was hoping for time between each run to adjust the a/f map but because of the number of cars being dynoed today they did 1st and 2nd run together and I only had a chance to tweak before the 3rd run. It turns out that when I unplugged the ecu a few days ago it did more then change my trim numbers, it also made my car run a lot richer in open loop. Unfortunately I didn't get a chance to do any runs before the dyno to adjust, so the first two runs were very rich.
Before the third run I tried to lean out the map but obviously didn't take out nearly enough, it was still too rich. Still, just that change increased the power substentially, the 3rd run returned the best numbers, 223 hp and 238 ft/lbs at the wheels. Quite a torque monster
. Note that the max torque is at the very low end, so if they started the dyno lower it would've probably be even higher.
Overall not bad, but not great. I bet I can squeeze another 20 hp out of it by simply getting the mixture around 12.5:1. Probably more with the smaller pulley In any case, it's a good baseline.
Funny thing is, there was a brand new WRX STi dynoed later that put down numbers almost identical to mine.
I'm an idiot and I accidentally taped over part of my run video so this is all that I have right now. I could kick myself

There were a few other people taking pics and maybe taping, I'll see if I can find a full video from someone.
