Fuel Consumption went up after the header+tune?

After getting my headers, I understand this better but will follow the diagram that HKS Provided. So they are reversing the position of the sensors: O2 sensor goes to the single front section and the A/F sensor goes towards the rear hole by the overpipe.

Installed! It went by pretty quickly. It rumbles but its not obnoxiously loud which is what I prefer.

Yes Jamaica! Well our climate is pretty hot yes. I have been researching on some cooling modifications to combat the heat but generally speaking, overheating has never been an issue for me. But I am looking to upgrade my radiator, upgrade my front diffuser underpants and maybe the oil cooler. But the oil cooler seems to be a modification for Supercharging applications.

The oil cooler will just let you run the car harder and longer with no power fade. That has been an issue before installing oil cooler. I havent taken to the track but I can beat on it all day and the oil temp reading will never pass 240f.

Someone on this thread mentioned the stock tune runs rich. Is that all MYs? I had a 2013, where I could consistently get 31-33MPG, now I have a 2017 and my mileage is ~28MPG with same routes/driving habits.

But I have noticed with the 2017 that my garage smells like gasoline when I start the car. Have others noticed their 2017-2020 tunes going rich from the factory?

I'm now reflashed with E85 so hopefully it's only a 20% drop in mileage.

Well my temperatures haven't spiked or anything for me to get an oil cooler just yet. I will continue to monitor it though.
