Need help
 

Took the truck in for service work. Uninstalled the i2. Got it home and went to reinstall and it locked up during the stock tune down load. The truck is totally shut down. It will not even crank. It says to service stabilitrack, low fuel, steering assist something. Shitting bricks. I start a new job soon and need my truck. Any one have any ideas?

Its 3 am and i can't sleep this has me so worked up.

What year and motor do you have? What tuning software are you using? It froze while uploading the tune or downloading the tune?

Sound so like you may have had a problem while uploading your tune. Find a mobile mechanic service that has GM programming capabilities and have them come flash your truck back to stock, then retry while they're still there.

Call Diablo, you're not the first to have this happen.
