Hi everyone I have 2015 TE, with 150,000 miles on it. I put magnusson SC on it 6 months ago circa 130K miles on the clock. Tires are yoko's geolanders 285/70-17. I also have a mild lift 2.25 on the front and 1.5 in the back. Otherwise, car is stock with no added wait such as steel bumpers. I had lift and tires since day 1 with 11k miles on the truck. Consumption increased a bit but not that much I would say I was consuming 11 to 13 L/100Km with mixed city and highway.

After installing the charger fuel consumption was normal, I could easily get 500Km on a fill up with 1/4 left in the tank. Recently I noticed that I cant reach 400Km per tank, and Have to fill up every other day. Computer is showing 17.5L/100km I think its around 20L/100km which is crazy high. No further mods on the vehicle so nothing changed. I have no lights on the dash and truck is running fine, no issues at all except for the fuel consumption.

Reached out to magnusson who confirmed that I have the latest tune and to go back to stock wheels and tires.

I'm looking for advise here as to what could causing such a high consumption blocked cats? Spark plugs? Air filter, MAF? I know the tires are heavy but its the same before and after the SC. Any advice would be appreciated. Thanks.
