I wanted to juice up my 2012 Cruze Eco 6 speed manual but I don't want to kill my MPG. I'm getting ready to install an intake and Muffler delete, I'm keeping the cats and exhaust resonator. I use this car for my work commute so I like that 40+ MPG. How does the Trifecta tune affect the MPG. I've heard go with BNR but worried it's to aggressive and It'll kill the MPG. Thoughts and advice.
