Your best off reading that link I posted...

Long straight roads are fine...

ie 3 gear empty dual carriage way, 3rd gear 20-25mph then to the floor let it pull right round to rev limiter then off, let it coast back to 30mph, then into 4th and same again.

Have you gotta do any mapping too?
We did my Scooby and Orion running in with no boost first, did a oil change, then back out and added boost plus mapping...
The Scooby was quite a experience with a 5th gear pull and 25psi round to the red line...
