No power after loading Diablo pre-tune

[4wheelingw/power]

I need a fix to run the Diablo (power and torque) pre-tune properly in my 2016 GMC Sierra SLT 5.3L.

I've loaded the pre-configured tune, but it knocks out the power to reverse and drive. No revs and/or movement.

I'm looking for all out power and torque, so if I can't load the Diablo pre-tune - then what do I need to tweak.

DOD - Off
Speed Limiter - Off
Throttle - 12% increase
Tire size adjusted - 285/45/22

What else?


Thanks
Felix

Save the attached file to the intune drive in your “My Computer” window. Then head to the vehicle and select the custom tune. Write it to the vehicle and let me know what happens.
