2014 Corvette will not start

[gtriplett]

Hi all - I ordered a 2014 Corvette Stingray from the factory a couple years ago and also ordered a Diablo tuner at the same time. Well I was a little nervous about putting the tune on the car but after doing the update, I went ahead and installed the 91 octane tune this weekend which went on the car fine but when instructed to remove the device and start the car, it was hard to start and ran very rough. I turned off the car and though I would restore to the factory tune, the factory tune went on with no errors but once instructed to start the car, it ran the same, hard to start and running very rough. I then tried a couple more of the included tunes but can not get the car back running. Any help would be appreciated.

I also had installed a throttle controller (vietmese?) and ma not sure if this would have had an impact on the install.

are you pressing/holding the start button to engage RUN mode in the car for each key on request?

have you tried cycling from off to run then starting it?

its not uncommon for these cars to idle a little off for a minute or so right after a flash.

Thanks
