1. After MD Spacer, zTube and K&N Filter install
2. After HR Y Pipe Install
3. After Grounding Kit was installed.
I've mentioned it somewhere in each thread to that mod including this one.
It helps especially with this one bc your ECU has to get used to the new airflow enhancement the HR Y pipe adds.
The ECU will adjust to the HR pipe on its own if you don't reset but it'll take longer further delaying the result of adding it in the first place.
Usually when I reset the ECU, I take my car out for a spin on Lake Shore Drive from my house to downtown Chicago and back. The entire trip is about 11 miles and by the time I'm nearing home, I begin to notice the new additional behavior my car exhibited due to its new toy. It wasn't like adding FI but it still was noticeable.
With the MD Spacer, I felt them right away before I even reached downtown. Resetting the ECU has its benefits
Please keep us posted on any vibration issue you may have. I doubt you may have any at all.

Actually make that 4 times. I also reset my ECU after I had the Berk HFCs installed as well.
As for your installs, keep us posted!
Are you also installing a K&N Filter and Revup Airbox as well? If you are, I'd recommend resetting the ECU. If not, I'd hold off until you do.
Correct me if I'm wrong, but I thought the only difference between both the gTube and zTube was the resonator in the gTube causing it to muffle the induction sound coming from your motor.
I'm not sure if it adds any additional horsepower or gains. What I am aware is if you do add the zTube, K&N filter and revup airbox you will notice some kind of gains.
If you were installing all of those at the same time I would reset the ECU.
Is your HR-Y Pipe in yet?

Not bad at all. The rears were super easy. Fronts I kinda F'ed my self and almost ruined an endlink. I spent a lot of time trying to fix it and I did so that was clutch.
I took my time an torqued everything nice nice. I did find one of the rear endlinks is getting stiff so Im gonna try and get it covered under the extended warranty.

If you have them out you will know, inspect the boot or seal, rotate it and see if it moves smooth. One of mine just felt dyied out.
