DCT...

I have noticed that the gas mileage has gone down from 20 to 16.5 mpg

Also wondering if it'll pass smog.

I did also see the temperature go up really really fast... to over 102f in a few minutes. I'm unsure if the car did this before the tune. I'm talking about the supposed outside temperature.

I ended up flashing it again (2 minute mode) to loud burble and it was too much, there were sharp bangs I did not like. So I rolled it back to medium.

I forgot to put it in airplane mode and realized mid-tune. I freaked out and put the airplane mode in the middle of the flash. The car did not like this and refused to take any more input until I restarted both the car and the app. For some reason bluetooth was on, it wasn't until I set it off that it worked again. Had a few moments of cold sweat there. While flashing, the car throws a lot of errors and will not start.

The risk of this is... something happens while flashing, and goodbye car.

On second thought, I think it's a bit too risky to do this for such small gains... maybe it'd make more sense on a modded car. Since I have already flashed, it I'll keep using it for a while and see if I flash back to stock or not.
