Have never bothered with a dyno. I suspect its running on the rich side when nitrous is flowing which is fine. I did take it to the track back when it was 100 shot. It had 245 all seasons that spun through first and part of second despite having the controller kick the nitrous on at only 50% and ramp it to full in 2 seconds. It would shut the nitrous off just before redline, so I could shift under reduced load, and then re-ramp it. So while being on the super safe side, it still managed a 13.7 @ 100.8 mph. The guy that helped talk me through my install did dyno and got 325hp and 340 tq.
After the fuel pump work, and 285's out back, I'm guessing it might sneak a 13.1 or even a very high 12 second run, but I have not been so eager to go to the track with this many miles. I suspect now its 350+ rwhp but the torque is much more significant improvement. Its likely 375+ ft-lbs rwtq (richer trades HP for Tq). Better traction, while letting you ramp the shot faster and increase overall area under the power curve, beats the driveline up more.
