Upgraded turbos

[city1991]

I've got a 2016 640 coupe. Love the car! I'm going to be doing a Dinan tune to it. Want to do catted downpipe instead of catless but the more I read it seems catless is the way to go. Upgrading the turbos to bigger and better, would that also help horsepower and torque? Thanks for your input.

Dinan is such a waste of money, there is so much better gains for less money. Run BM3 for 2x the power and 1/2 the cost. High flow catted are not worth the money imo. The biggest gains will be with catless. Again thou Dinan is not going to push huge numbers. BM3 with catless dp would give you massive gains.

Unfortunately I already bought the Dinan 10 months ago, so no going back. It does say horsepower increase to 369, and torque to 470. Which are good gains. I need to get more information about catless. I heard going catless you get gas smell in the cabin, which I obviously don't want.

You do get some smell outside the car, inside nothing. Even with windows down it's very very light, if anything, inside. Big gains for catless make up for it in my mind lol.
