Manna Indian - best recipes at home to replicate as close as possible!

This place has ruined me, as the chicken tiki masala or butter chicken are so incredible. We have followed what feels like 10 different recipes, trying the exact ingredients and we cannot get close...

Does anyone have a recipe for the tiki masala or method that gets close to this? At Manna it has such a deep flavor, almost a gravy with brown in it, and at home it continues to be two tomato forward or acidic, without any of that deep flavor. What are we missing?

I get that we will never get to that quality, but just trying to get closer when we are craving it and don't feel like a 90-minute round trip...

I ask here because I see a lot of people mentioning it correctly as the best Indian food in the city (by a mile if you ask me), so I'm hoping someone else may have gotten close!
