I am hoping for at least 330rwhp later this week with my low compression 4.8L. That is before the turbo of course

That and the big wheels and massive brake rotors.

Don't get me wrong I'm not unhappy with the results.
I just know it can do more.
What nitrous kit and how big of a shot was this with ?

What other mods do you have ? Just bolt-ons ?
