There just the stock O2 sensors before the cats, mine were running really sluggish so was time to change. Do you have any pics of your tips? Looking for ideas for a new set on mine

Damn mike make up your mind

I'm going to stay mostly stock with some all terrain tires and maybe ford keys and a 1" spacer but going to stay on 265's and no bigger. I need her to be able to still go to the snow, get better fuel mileage and be more practical than what it was. Plus my wife hated driving it on 22's and didn't feel safe. I'm the type of person that puts family and safety needs before personal needs.

@ Vince, Thanks. It will definitely be quite some work to do a monitor, the stock radio panel just pry's out, no screws nothin...

@ Tahoenjn, Chip, Thank you. Im gonna try to make a little write up on it as soon as I get back in town.

Just got my EFI Live tune, man when you punch it this thing gets up and goes balls out. Cant wait to see what kind of mileage I get now, well after a few weeks off lead footing it of course.

Installed Z71 Springs from a Suburban Z71, Re-Installed my Stock Keys and got new tires for the stock Tahoe NNBS Rims. I know it looks plan "Jane" but the ride quality is so much better



I also reworked my back up lights.
