It's very satisfying to watch

Cool! is that stock boost? Or is it tweaked?

 

[V8Astro]

Good question! It's a GM5 turbo on a 6.2 with an EBay wastegate actuator. I have it set to 7psi. Not sure what boost the 6.5T maxed at.

Most guys say 12psi max for the 6.5TD and set them around 10psi.

 

[V8Astro]

Wow that seems high. I think with the comp ratio of the 6.2 I'll leave it at 7psi (I say that now)

I have been running 9 psi on my banks sidewinder setup and it works great
