Can you still unlock a i1000

Ok thank you for the input.

I found a granatelli 990917 programmer for a 03 hummer and was wondering if I could update it and use on my 06 Silverado?

Yes that is the one. Yeah i used this account for a company i was working for. lol. Just have the message This vehicle is currently not supported; an update may be required. Please plug this device into a pc to download any updates. Says nothing about unsupport files

I have a 2006 GMC Sierra and bought an i2 tuner and everytime I plug it in to the vehicle is says that vehicle not supported. I have contacted holley have reset and done updates and still have issues. I love your products and would like to use this on my truck

Thanks
