What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Got my rear bumper hitch cover today.

Is this from GM or aftermarket? I'd love to get one on my 14 Yukon SLT.

3.08 gear Phil?

I remember @badandyturbo Andy's Tahoe has a tune and he added those Amazon long tubes and makes a solid 320 RWHP, 20 HP more than mine which just has a tune. If I remember right, his ran 15.40s.

And Ken, too many changes now brother! Going to be hard to know what's done good and what did nothing and what might have hurt. Speaking of hurt, how's the differential?

It's been fine.. no I'll effects.

I got thinking about it and I remembered that I have one mismatched tire on the rear end. I wonder if that tire being different had anything to do with that issue.

Not sure [emoji1745]I've never changed them so if that is what is stock from factory, then yes. I have the Dyno results somewhere on here or at home. It was putting out 307 at the wheels and torque was 290+ I think. That was with 22's on. I'd like to change some things, but it is still my daily and family hauler so i want to keep it somewhat of a family car. I just have a lot going on and we are trying to buy some property (cabin and a few acres) so the Tahoe is not high on the priority list sadly.

I don't remember the details of your truck Phil, so it may have 3.23 gears (GU5), 3.42 gears (GU6) or 3.73 gears (GT4) or 4.10 gears (GT5). Does the inside of your glovebox still have the RPO Sheet?

The cabin and land is awesome, make that a priority, the boys will love that for sure!

Last time out, mine made 307 HP too through the traps.
