Hello all,

I am looking for the factory Magnuson TVS1900 kit tune for a 2010-2012 Chevy Colorado/Canyon 5.3l. Mine is a 2011. This would be the tune they send with the kit or after tuning the ECM with their programmer. I have a used kit(sort of) and no tune file. Needs to be the original from Maggy to get through emissions. Thanks for looking.
