Hey guys, I've had my Q50 3.7 AWD for a coup[le months now, and my end goal is making it one of the fastest ones out there without adding turbos and supercharges, etc. I'm looking for the safer option seeing as my engine only has 43K miles. I've got a muffler delete and that's it. I plan to get cold air intakes wheels brakes, possibly a cat delete, and whatever else to slowly increase performance, then I will go for a one-time tune. With the tune I'm looking for something I've seen on this forum somewhere, the guy had a pop tune, flame tune, speed tune, and fuel economy tune all in one, that is the goal for my Q50. Thanks yall!
