Probably not what you want to hear, but an 8psi radix kit, and TOG's with your current stall will get you damn close to low 13's. Have you started installing the vortech yet?

Well you're hear now to learn before doing anything. If you can return that Vortec and that Alk kit, I'd do it. The Radix is what you need for your Tahoe/Yukon. It makes power off idle where it's really going to make a difference. That centrifugal kit is better for light, top end racers.

Hate to keep bringing this up, but maybe if you told the vendor you'd be trading for a radix, they'd go for it. It can never hurt to call and at least feel them out. Even if you have to eat shipping.
