Cobb has updated all of their tunes and are running version 506. I am convinced that these updates are more competetive with the tuner OTS maps. Here is what I consistantly read off of the AP, caveat being these numbers are computer generated but still seems reasonable to compare relativly. 93 octane
Cobb Stage2 (ver. 506) : 220hp, 273 torque
Dizzy Stage2: 197hp, 250 torque
The tuners (tune+, Stratified, Dizzy, etc) are based in the older versions. My Dizzy and Strat are running Version 500. The plus side of the tuners is the customizability, but I have been most happy with Cobb's newer versions. You can always just switch maps to suit your driving style
