I got my Budget y-pipe yesterday and I will be getting a Budget b-pipe on Saturday. I want to dyno after that but I was wondering if I should wait a week or two for all the material to wear through properly and for the car to get used to the new pipes or would it not make a difference if I just reset the ECU the same day and went and dynoed immediately.

Thanks for any advice here.

 

it shouldnt make a difference, go for it!
