Toyed around with a friend's GTech Pro with my old WRX and it was fairly accurate, compared to actual dyno numbers. The main thing was calibrating the exact weight of the car as that has the biggest affect over everything... not sure about the Vector but it's probably similar.
By the way. 383- 770 Holley Street Avenger, Edelbrock Perfomer RPM manifold, I am not numbers to post for my cam but I have them. ADV INT 272 INT and 272 EXH/ .050 Dur-216 INT and 216 exh. 4340 crank. world class heads. TH400 and B&M holeshot 2400 stall speed.
How can I get better results? (besides trying to reduce wheelspin).

Reason: More info
If you do a derivative on acceleration, you get velocity. If you do another derivative on velocity you get distance. Its all based on calculus. Since acceleration is 0 at start, its not a real tricky calculation. But don't ask me to do it, it's been way too many years since I did that kind of math .
yeah...that is a cool new toy. I got a G-tech last year for x-mas and used it several times including the track. It was dead on after I made all the fine tuning adjustments such as weight and rollout when starting at the starting line in the 1/4 mile track. The track I went to had no problem with me using it...so I used it and got it dialed in consistently to less than 0.05 secs difference in time slips. It told me how slow my shifts were, etc. The dyno was dead on the money but you definitely have to weigh your car to get a correct figure.
