Dyno time

I am putting my type-S on the dyno Saturday 2/8. I have an AEM cold-air intake and a Thermal cat-back. I wanted to have headers on before my 1st pull, but it does not look like that will happen. Income tax check will be coming soon though. Does anyone have any tips b/c I have never dyno'd before. I will post my results and what kind of dyno it is b/c I am not sure yet. At least it will be cold sat.
