lb7 CTS Insight
I know you can switch through your efi tunes with the CTS INSIGHT on the lb7. My question is do you have to run all 5 tunes or can I program it for only two tunes? My truck has the stock transmission so for now Im just going to do a heavy tow and a 90hp tune. or will i have to have 3 stock settings and then my heavy tow and 90hp tunes?
