    Hello friends, I decided to go over my most recent log tonight (first time actually looking) and saw some alarming numbers that just don't make sense.

    How can you tell if you have a bad tune? Also if a well reputable tuner doesn't offer the right tune for you and does it anyway, which now leads to a bunch of problems, are they at fault in any way.

    What is the difference between JB4, ecutek, or going into a shop for a tune? Idk what the differences are between these. Would a shop use a jb4 or ecutek or do they use something else.

I just got a 2015 AWD Q50 with the 3.7L, I'm thinking about ordering a catback and/or axel back exhaust for the car, along with a CAI, but I'm not sure if running these mods without a tune will do any damage to the car over time. Will I be fine without a tune? Will it throw any...
