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

How can you tell how much higher than normal the rear end is when you're in the car?

it's like driving in 2 inches of water you know when you drive threw standing water it slows down a lot


there was so much weight collected at the front end the rear end was up 2-3 more inches then normal

I'm not sure I follow you on that last comment. When the KO2s were new and hit a large puddle on the side of the road, they cut through it like butter, no steering wheel jerk in up to 3-4 inches of water. Similarly, when we hit a torrential rain storm once, there was 2 inches of standing water on the road and the truck did not flinch hitting that at 80 mph and maintaining that speed until traffic forced us to slow down. Pretty amazing to me. I was thoroughly impressed with my BFG Radial T/As when the new tread pattern first came out in the early 1990s and these are similar but even better.

I have driven through lots of snow in my day. Deep snow even. Done it in RWD cars, FWD cars and 4WD/AWD vehicles. I have never experienced, to my knowledge, this phenomenon of my rear end lifting 2-3” because of the resistance from snow in front of my front tires. Can you please elaborate on what it is you’re talking about?

Also, I can understand that if you were driving at 35mph in your “snow event” that you would see a reduction of fuel economy, mainly due to only going 35 mph, but 50% seems a little drastic for what I would expect. How much snow did this “snow event” drop?

extra Weight collection on the front this was "wet snow" at lest 40pounds collected under the bumper


it has the nivomat shocks (ZW7)

lol, 225lbs on the front bumper would not even make the rear bumper budge, ask me how I know

Almost finished the LTZ dash swap in the Silverado. It all started with trying to install that damn Esky cluster lol.View attachment 237337

That is looking damn nice!


I played with HPTuners today. Got some burbles now! I have it set so that below 0.2 grams of cylinder airmass between 2,000 and 4,800 rpm, it will drop the timing to 8* before top dead center. It won’t do it on deceleration because it opens the throttle too much, but reving the engine in P or N, it will sound like this.

Damn!! Sounds great! Sounds like you have a cam.

Texas Speed Low Lift Stage 2! IIRC 212 intake duration, 218 exhaust, 0.550 lift on both lobes and 113 lobe separation? I have a pic of the cam card around here somewhere.
