Do you still get the rattling?

I'm going to check again just to be sure and also that it's the same as before, but I think so. I've probably got used to it somewhat. It's most noticeable when car is fully up to temp.

Mine is ALWAYS there at 2000rpm, very easy to replicate. I’ve got a recording of it, it’s pretty bad. I’ll see if i can upload it somehow

Bizzare! I wonder what it could possibly be if not an exhaust rattle coincidence. Something to do with our recent tunes from same place?

Did it sound like this?

This has happened since day 1... It was there when I picked the car up from their shop. I was very surprised that they gave the car back without fixing it even though the car was there for a month.

Only ever happens ~2000 RPM

No not like that. Mine is of less "frequency" than that and most noticeable when just idling at a standstill when everything has warmed up.
Yours sounds like maybe an exhaust leak or the exhaust is rattling on something or is loose maybe?

Honestly, it sucks. For the money I spent, I was hoping there will be no issues, if any, very minor ones... During the whole installation and tune, I continued to agree with the shop's advice on whatever they recommended.
They were on Christmas break when I tried to reach out to them about my concerns but I couldn't get support from them...

I had another tuner check out my data logs since I'm not familiar with all these technical aspects. Jeez did I open a can of worms... I have been advised not to drive the car at all because the tune is that bad...

Really, the last thing I want is to make a big deal out of this. When you pay for a service, you should expect to get what you paid for.

It does sound like the exhaust is hitting something. When the tuner came down to adjust my tune, he said it sounds like exhaust drone but he will have a look once its up on the hoist. I'm certain that's no exhaust drone... My exhaust set up is invidia gemini + invidia hfc. Surely it can't drone to that point otherwise I would've heard complaints about it from other members already.
