Hello mituc. So, My question is. I need the updated fuel pump internal for this tune?. I see that only these active pops & crackles at 4K rev. That's great. Please confirm me.

Hey!
No, you do not need to upgrade the pump internals for this tune. The pops&crackles are done only on decel where the required fuel amount is minimal.
However, if you will see fuel pressure issues with this tune then most likely you will see them even on a stock tune, in which case it'd look at the upgrading of the pump internals more like a fix rather than an upgrade (of course, it would be a significant upgrade, but applied to fix a failing worn part).
