I bought a U7194 for my 08 Gmc Sierra 2 wheel drive 6.2L. Version v.8r10. I Installed a K&N Cold air intake. Will the 93 Tune be sufficient with the K&N or do I need a custom Tune. Also how do I eliminate Torque management. The shifts can stay the same as the site recommends for trucks.

can't adjust any tranny stuff for your truck - so there's no TM settings for the tranny that you can adjust...
the TM is already reduced/removed on the engine side of things in the diablo tune... there's nothing you can adjust...
no need for a custom tune, just drive for about 75 miles, then do some logging and get your LTFT's dialed in by adjusting the injector slope as needed... here's info on how to do that:

^^^ So there's no benefit to a custom tune over dialing in the LTFT's?

sure there is...
I can do a bunch more than you can with the handheld predator via a custom tune... but it'll cost ya...
