If you want to verify your gains
Do before and after on two different dynos.
That will give you an independant comparative.

Thats what I've proposed - so were in violent agreement.

Instead of 0-100 and 0-80 acceleration runs, consider doing in-gear acceleration runs, second or third gear. Ideally these should be videotaped from a position where the rev counter is visible. Then you can get a very good idea of what the difference is in given rev bands. Good point. Lack of acces...
