Hi everyone

I am needing a 2010 Hummer with 6.2 liter engine to do a compare in Tunercats .Cal format

Anyone have one I could get, would help solve a problem where someone did not tune this vehicle very well
and I need a stock cal to do a compare and and correct the existing tune in PCM ?

Thanks for the help
