Ok guys, still working on the tuning, but I thought I'd share the quick assessment on boost pressure comparing my old set-up vs. new...

OLD was with the Katech Standard Port + 8 rib (showing in two pulley sizes)
NEW is with the KONG XPORT + 10 rib ((showing same two pulley sizes)

Result... the XPORT + 10rib was worth 3 psi peak on the 2.4" upper and almost 3.5 psi peak on the 2.3" upper...

Although we have alot of tuning left to go I can tell you that the difference in power is VERY noticeable.

Should be able to strap her on a dyno in 3-4 weeks. Stay tuned
