Sorry but couldn't find the answer on a quick search. I had a Screaming Eagle intake and Pro Street tuner installed together. 2 weeks later, I installed V&H Long Shots with the quiet baffles (I'm in Commiefornia & old, don't need that much volume from my pipes). Let the bike run, sounds good, idle is good. My question, do I need to get it re-tuned & if yes, how quickly?

Thanks for your help.

 

The simple answer is no. That said your bike seems to run just fine to you without recalibrating the EFI for the additional airflow, right? It’s also the best running you’ve experienced. Get it recalibrated (tuned) and you will feel the difference.
The best way to evaluate your question besides asking for advice, is to talk with folks who have made the mods AND got it recalibrated by a competent tuner.
