I wouldn't recommend it. If your Tahoe is your DD and you don't plan on racing it then I realllllllllllly wouldn't recommend it.Well I figured it would be a fun little boost of HP to go along with my soon to be BB tune and besides the looks don't hurt either. I'd never take my tahoe to the drag strip but for where I drive sometimes long flat empty roads id be nice to get a little kick and have more fun while I drive.
