Best tip you will get is remove the swirl flaps if they are not. They tend to break and go straight to the cylinders, and the engine needs rebuild. Anyways, they leak air also, which makes the car sluggish and with higher fuel consumption.

@@JoJanDiezel yeah I had to fix the oil leak by buying a new hydraulic kit and the rest is fine the last owner added some extra features such as more electronic stuff, most of the engine problems fixed and others. Not gonna lie really a great car as a first car! 150hp turbodiesel, black leather seats and tinted windows I can't ask for anything else it's like a baby Ferrari

No, it is an Inline 4

Probably remap

Boost pressure?

I'm 8 months late, but since he didn't respond... I have the same car and same engine. The one in the video is probably remaped, since the stock tune doesn't want to pull above 3500rmp. I have it stock, and the consumption is about a 7 driving both in city and open roads. You could bring it down to about a 6,5 if you drive efficiently.

@@adrian55051 thank you very much for the answer :D
