Hello I'm new to tuning, been doing it for about 3 months now trying to obsessively learn best I can. I signed up here because I love holycrapitsfast tuning guide (the best I've found), I also use the ones by Cobb and Badnoodle.
I have trying to figure out why I get a dip in torque and HP and how to fix it. I also get a count of knock or 2 if I give it WOT at 2000-2200 RPM. Having trouble figuring this out so I thought I would post up on here.
I have a 2016 STi
