Great upgrade

I added this billet wheel to the GT4094R in my 03 LB7. It is a drop in replacement and fits perfectly. The machine work is very impressive. Low to mid spool is slightly faster. Top end is where it really comes alive. I am seeing 42-43 psi boost @ WOT on a 500hp tune. Looking forward to seeing what it will do on my 620hp tune.
