Recently got my car tuned, and went catless, I got both a transmission tune and ECU tune. It is mapped for some burbles/noise but not a lot at all. I’ve been driving it for about a day now, maybe 20 miles in total, 5 of those being in sport, and I’m averaging 10mpg LOL. Will the tune eventually learn and I will get better gas mileage or am I screwed?
Thanks
