Greg over @ pheonix transmision did mine as well...

 

I ran the Vinci 062 cam, MP112, 5.3L in my Tahoe. With the Radix I have always run a 2600 stall. I did with the Fuddle, which was replaced with a 2600 Vig triple disk (awesome by the way) and then a Vig triple disk when I went to the 4L80e, also a 2600rpm stall. I think anything over 2600rpm and you're wasting all that low end, "under the curve" tq that the magnacharger is designed to make. Why make 450lb/ft of tq from 2200-6000 if you'r gonna flash to 3000+ on the launch? Just my opinion.

 

Vig 2600 here and no probs!!!
