Dyno question - test pipe before and after
I have a Comptech header, exhaust and drop-in filter installed on the car. I also have a Comptech test pipe ready to be installed. (I'll put on the SC in a year or so). My question is this - does it make sense from a curiosity or technical standpoint to do a before and after dyno on the same day that I have the test pipe installed? The reason I'm asking this is that I've read that the ECU won't have time to adjust to the new set up and a before and after dyno would therefore be useless. Would it make sense to do a dyno after the install to check the A/F?

Dyno is really more for your own personal gain. You can find out much HP your putting out with the TP. Your A/F should stay about the same, nothing dangerous -- at least that is the case with me

I say do it and tell us the outcome. I am interested.

The ECU won't "learn" immediatly but in a week or so it will correct everything and you'll be fine.
I would like to do it immediately because the conditions will be nearly identical.

You'll gain peak HP as long as power throughout the whole powerband.
Its probably not a week, I'm just saying that to be safe. The difference isn't very much between it "learned" and "unlearned"
Note that I made more then 15HP peak and 10 TQ peak with a testpipe. Plus HP and TQ gains throughout my whole power band.
