My 2016 Silverado 5,3 is making 572 rwhp. It’s been through a few dyno runs and 4wd WOT street runs and does okay. Actually in 4wd traction control off it reaches right down and gets it. I’m going to take it to the drag strip in a couple weeks and try with some higher alcohol. I would not be excited about breaking anything.
Just wanted to know if I should be concerned getting up to E20 or 30.
