Flashed the 2.0 update for Shiv's Stage 1 tune. Initially, throttle felt limp, but after about 10 minutes, everything was back to normal. Not a huge difference, but power delivery does feel smoother from 4000-5000 rpms. Definitely don't get the surge in power you got on v1.5x. Drivetrain noise seems to be about the same, but tough to tell due to modified sound tube. Noise is still very good!
Also, been noticing difficult to remove bug guts on hood and front bumper. Don't want to scratch up paint by scraping them. Will try some bug+tar remover from home depot a friend recommended and report back.
Also have noticed windshield has what looks like thousands of little rock chips. Became really obvious after detailing both interior and exterior this weekend. Not a huge deal, but makes windshield always look dirty. Still repels water very well, so do not want to replace/patch at this point.
