What did you do to your NBS GMT800 Tahoe/Yukon Today?

[Rocket Man]

I got my American Racing headers today. Now I have a dilemma. When I installed my AEM wideband gauge, I followed along with some advice and installed the sensor downstream of the cat on the driver side and had the downstream sensors tuned out. But it seems that my readings aren't accurate since they fluctuate wildly, and the instructions say it should be installed upstream. So I have 3 choices- install it the way it is now, install a bung upstream and plug the downstream bungs or install a bung upstream, buy new downstream sensors and have them turned on in the tune. Any suggestions?

You're going to have issues trying to run the rear o2 sensors with headers since the cats are so far downstream. BB tuned mine out and will prob recommend the same for you. Maybe it's not as bad with the ARH headers since they are high flow cats for the af gauge.

My downstream ones are already tuned out.

Just ordered 4 quarts, and the free can of Kroil.

Been using SeaFoam for a few years, and recently have seen an improvement in both power and mileage by using Lucas additives. We'll see if the Kreen does any better!

Does it get added to the oil or the fuel tank?

It will. The Kano folks have incredible products.

I put those different 22''s on the fronts. I wanted to see if the shaking would go away. I think it has. So I'm gonna swap the tires out and hopefully that's my issue. Looks so ghetto. View attachment 85426 View attachment 85427

Shaking is def gone. Got it up to 80 and it felt pretty good.

Hopefully the shake is in the tires and not the rims themselves.

How long since they were balanced? Could be the rims too. I still have a shake around 70 but it's due to 2 of my tires being out of round by about 7% they said.

 

[Tonyrodz]

I had them balanced twice. Last time was maybe 1 1/2 months ago.

Maybe out of round like mine. It took someone with a different balancing machine to find out. They balanced fine but he's the only one to say they were out of round. Hopefully that's it or else it's the rims.

The chrome ones ride nice, but they're so damn ugly--to me anyway.

Went up to brown mountain ohv and took the yukon offroad. not too rough but there were some steep rock climbs and lots of rocks for the toyos to claw on.

D-d-d-dip 'em!

D-d-d-dip 'em!

I may have to if the other rims are bent. Also missing one center cap. Which sux too.

Big difference looking over the hood !!!

Looks great man!

Yeah I know. It looked like option 3 was to buy new downstream sensors and turn them back on. I would try them behind the new cats and see if it's a problem first. I've seen it go both ways and would try the ez option first.

Looks like my luck has run out with the 4l60-e. On my way to my girlfriends house this morning, I was having all sorts of problems. Clunking, didn't want to downshift, slipping...

I guess Ill drop her off at the transmission shop tomorrow and hope for the best.
