Hey folks, I previously had a 2002 Z06 with an APS TT kit, tuned by me using speed density, ran great.
I've been out of the tuning loop for some years and a buddy has a 2009 CTS-V which he wants to dig into a bit.
Just curious how much things have changed in the factory maps and tuning procedures since I last tuned my 2002.
I have the MPVI Pro cable and will need to grab some credits for his car.
Not looking for any real definitive info, just maybe some tips and things to look out for.
Could there be any changes and software upgrades I may need?
Thanks in advance for any information.
