I'd suggest more than 3 passes.
At least 2 passes per each variable so that the 2nd dyno run can validate the first run. For example, if Run 1 with the Megan TP is drastically different than Run 2 with the Megan TP, than do a 3rd run. Hopefully the 3rd run will be similar to one of the previous 2 runs with the Megan TP. If it is, then swap out the Megan TP and move on. 1 run for each scenario is not good enough.

I can't wait to get the car on the dyno with those test pipes and add to the hole in the ozone layer....No, I'm just kidding treehuggers, test pipes are bad...BAD!

Just curious, with a NA car, does removal of the cat result in a lot of black smoke when you gun it? Mine did so I put the cat back on, but I'm S/C'd.

Well I got my car dynoed again to see how much power I picked up by going catless and man did it pick some up!
+16.1HP and +11.1TQ all with just taking the cat off.
I

^ there are simple ways around a CEL caused by a TP...easiest and most cost effective is 2 spark plug foulers tapped into the TP where the o2 sensor goes, the thread the o2 sensor into that...it holds the sensor out enough to trick it.

where did you get your test pipe from? Does your check engine light come on or have any other problems?
I did the spark plug mod that efthimios is talking about. Sofar about a thousand miles and have yet to see a CEL.
Only problem I have now is not being able to listen to my car on the dyno because it physically hurts to listen to it
