Dyno time booked

Well,things went good and I'm happy with the results.

Run#1) 261 rwhp / 264 rw tq / and the a/f ratio was an average of 12.1
Run#2) 257 rwhp / 261 rw tq / and a/f ratio avg. of 12.3
Run#3) 256 rwhp / 263 rw tq / and a/f ratio avg. of 12.3

N2O run #1) 324 rwhp/340 rwtq/ a/f ratio avg. of 11.0 !
N2O run #2) aborted

If you figure about 17% drivetrain loss thats right around 300-305 engine horsepower,which I'm happy with. However my a/f ratio is dead rich. The average numbers don't really show the whole story. It was fine at part throttle(14.7) but as soon as I went to full throttle,it would quickly go to poop. If you take out the part of the graph that includes the part throttle portion,the averages drop(by my calculation) to around #1)11.4 #2)11.4 #3)11.2 . So some adjustment there should net me some decent gains. I'd hope about 10-15 rwhp,maybe more. The nitrous run was with the 100 hp jets and the bottle pressure was 1100 psi. The first run was with the flip chip in the normal(OFF) setting. I forgot to bring any other jetting with me so I wasn't able to tune it a bit by decresing the fuel jet size. The 2nd run was with the chip in the nitrous position,which has the a/f ratio fattened up for safety purposes but it went too far. I cut it short cause it was loading up the motor,making it stumble and was getting worse. The a/f ratio was actually at 10.0 and falling when I stopped. So definately lots of a/f adjustments to be made across the board,and all for more power I hope.
One thing I noticed was that the torque seemed kinda low and I'm not sure if it's just a Mustang Dyno thing or if perhaps a setting on the computer was wrong. I was expecting about 20-30 more foot-pounds N/A and about 35-45 more on the nitrous,I guess we'll see once the guys have received more than just the basic training on the dynamometer(spelling?).
Also temperature inside the dyno cell was about 19 degrees celcius but the engine temps were not particularily low. #1) 200 degress F #2) 220 degrees F and #3) 235 degress F. (1/2 to 3/4 up for you guys without a aftermarket temp guage)
I guess I'll have to make another trip once I get my chip reflashed again. I'm thinking of going to a Diablosport Predator tuner to gain some self-adjustablity. Then I can dial it it perfectly myself. If I've left anything out,just ask and if I can I'll add the info.
