Superchips for ecomomy and driveability? What do you think?
Installed a K&N filter. This is a 2001 yukon SLT 4x4 regular.

YES Superchips for economy and drivability, I think is great I have one and when you lower the shift points to it's lowest and stiffness to it's highest it will get rid of the slipping at does high RPM's and you do save FUEL you will make that acceleration more worth it specially when your in the freeway and want to catch up to someone transmission shifts better.
