So I emailed Jestr Tuning...

[dxbtune]

Can you beleive that the dyno broke 2 days before we get to try, got a call today...
Maintenance reasons...posponed how common do these machines break..grrr

[Warrtalon]

Very rare, but it does happen.

[dxbtune]

Apparently the software has a problem and they need to fly in a tech from Australia...
It works but the numbers are low so there is absolutely no point in doing it.
Waiting on the next date (dxbtune impatiently on standby) heh

If it is from Australia, if is probably a mustang dyno, or a dyno dynamics. Both of those dyno's read "low" compared to a dynojet. When a shop gets enough complaints from customers who want a "braging rights" dyno sheet rather than an "accurate" dyno sheet they call in the tech to teach them how to make the dyno lie and give big numbers.
