If you do it in D3 you could downshift when you puch the gas to get your numbers. Locking it in 3 with sportshift eliminates any shifting concerns.
BTW - on my first dyno I forgot to take off VSA. I couldn't get over 30mph or about 2500 or so RPM.
I was so embarrassed.....

The reason the dyno is off is because it was dynoed in 2nd gear and then upshifted to 3rd gear. During the upshift, the dyno spiked causing abnormal numbers to be recorded. During a dyno you should not be upshifting or downshifting. In a TL, the car should be dynoed in 3rd gear from as low an rpm as possible up to redline. NO SHIFTING! If you read his dyno properly, eliminated everything after the upshift (see the RPM chart and stop where the RPMS go down), he made about 200hp, which is right on the mark.
I hope someone actually read it this time.

Ill take my car back to the dyno and let them do it again. I dont believe the whp is that high as I mentioned in the beginning. I think its to the flywheel, but oh well. The dyno is in Wellington, FL so if anyone near there want to go let me know. On thursday its $35 dollars for 2 pulls and its very packed if you go after 8.

Go watch some dyno videos of other cars, see if they ever upshift after they hit the right gear. You'll hear them row through the gears till they hit the right one (3rd in our case), and then they gun it until redline and shutdown... they don't gun it in 1 gear, upshift, and keep gunning it ... thats not the way it works. If you don't understand how dynos measure horsepower and how horsepower and torque work with transmissions, you can goto http://www.howstuffworks.com and they have some very good explanations about how cars in general work.

OK guys, we've all had our little laugh at UglyPsycho, let's stand back and give him some breathing space...no need to keep picking on him. FWIW, he shared his dyno so that we can give him advice on what we know is to be right, so that we can correct him. Remember, this forum is to educate other members who are not as knowledgeable as us, not a forum to trash others. Don't give him a hard time about this, he already feels bad (I think).

I can post the explanation a 4th time if you want? That doesn't include the 5 other times someone else explained it. I'm just joking with you UglyPsycho, no hard feelings!...
