nah i haven't been on there in 4 years or so. and when i was .. it was extremely limited answering business questions. but the amount of dumb $hit i get asked and hear, i immediately know is coming from that hole.
weird. my 17 got 20+ but it had Dynomite 45's .. best injectors i have ever installed by a land slide. was 16.5 before that . easy 3mpg gain with only change being injectors.
i dont have the image here, but on our 2020 we gained 16hp simply changing intake, bone stock no tuning. can post dyno sheet if you need to see it, but it did it in front my very own eyes.
