duramax tuner is coming out with a direct drop in stealth 67.7mm iirc would be a pretty sweet turbo to make around 650hp on. + its a easy turbo swap.
The danville one is pretty simple to install I thought? Plus I'm pretty sure its capable of 850.. checking now
Maybe I'm capable of it with my injectors..
My thoughts are, timing and EGTs kill pistons. water/meth kit + 68mm = happy stock pistons? right? lmao. Just get a tune that would keep it around 650 and then a max effort for when I just want to spend more money.
