you have to drive it fer awhile let the computer learn new settings i have 6.2l silverado and i don't notice much diff between the shift settings either, best noticable setting diablo mode, hard shift, torque mang off, with good gas and you will be smiling.

Agreed, the Diablo Tune 91 Octane is awesome. I have a Jeep 5.7 Hemi, I also upped the throttle boost by 6 and I notice the difference
