Guys I have a 2011 6.2 with a Lund tune from Lethal performance. So far that is my only mod. But I'm feeling that this truck is not going to match the performance with only bolt ons that my 2008 Tahoe offers. Will a cold air and cat-back help with this?
I should elaborate: the Tahoe has the 6.2 Escalade/Denali motor with a custom tune, cold air, and 4.10s
