Mine is a bw s366 66mm .91ar 2.25" in 3.5"downpipe dumped behind cab
Running 10psi for now....have only drove it bout 150 mi after tune and very good street manners...and havent got it on a dyno but im pretty happy...sounds awesome too...
Prolly being laughed at for havin that small of a turbo lol
But i sure like it...
Pretty confident that its over 450hp...

Putting a tc78 on my 4.8
Plenty for what I need. Mostly for cruising n DD. And reliability but still got some punch to it.
Still using upgraded 60e and that tc78 spools almost instantly on a stock cam 4.8
