Duramax Third Generation: 2006-2007.5 (LBZ & LLY)
Hi everyone ! I need advice since i just bought my dream truck, now i want to safely build it to run daily 500-600hp.
I know that trans can hold up to 450hp
Now what would be the safe way to do it step bybstep? ( i already have egr deleted, cold air intake , exhaust and a tune )
