Good time to invest on a Good aluminum one

This what I need with my Yukon haha. I got it tuned on e85 but I never touch tcs or go crazy on turns. I’ve driven awd my entire time driving. I got the rwd version so 460wtq just blows my tires off completely from a stop or slow roll. So trippy feeling the back end sway when I’m smashing the gas. I imagine it’s only gonna get worse once I do the bolt ons. I noticed the tires that are on are completely trash. They don’t hold traction at all.

They use parts that can handle the abuse. They aren’t gonna slap on a shiny new cam if it’s gonna break quickly.

So damn tuning this thing will require fixing a lot of this before adding a lot of power.
