I have been working with Wedge on a 93 map and here are my end results based on a 4th gear pull using Virtual Dyno. I plan to have my car put on a Dynojet soon but the numbers are usually very close if you use VD correctly. I am very pleased with their results. Car is a Z4 35i.

Those would be good numbers but 99% of the time Virtual Dyno is garbage and calculates at least 20-30 higher at the minimum given what I've seen when people take the car to an actual dyno. I found its ok to sort of measure gains but even then unless you do a bunch of runs and sort of look at averages its just lame. Lets just say I used it on my M3 logs and I was SO proud of my numbers LOL

We will see. If you don't use VD correctly then the numbers are often wrong. However, if you log on a flat stretch of road, have the weight, tires and gearing correct then the numbers are pretty close. Most people don't know how to log correctly or have the other numbers wrong.

Trust me I tried it out making sure everything is done on flat level and all info entered correctly the numbers are just bogus. Report back though when you get to compare them. Are you guys fixing those boost spikes in your log?

You are right. Virtual dyno is a good tool when used right since the fans of the chassis dynos are not big enough to simulate the air flow.
