2008 Yukon Denali, 135k miles, part 2!!

[tgui]

Engine and trans tuned. Stock VE table updated. MAF tuned, timing adjusted, fuel leaned out a little. Trans also tuned. I paid for help on this since the GMT900s are much more complex. When I learn more I'll do the tuning on my own.

The trans shifts fast and hard. There is now very little torque management on shifts. Even on dry pavement I chirp the tired when launched.

Farting around....

Sounds mean, and I'm sure it's night and day difference from the ol' five three.

The Gen3 5.3 was a slug compared to this 6.2. The lower first and extra gears really help as well.

I replaced the plugs. The passenger rear wasn't as bad as people say. Just have an assortment of extensions and go from underneath a little.

My friend says the old ones were recently put in. At least I have peace of mind!

I also installed new 118db horns. Hella Supertones.

I have a set of piaa 115db horns I'll add soon as well. DC driving necessitates this.

Installed and loud!

Sound clip!!

I did the Velcro behind locks mod. The inside is sooooo much quieter.

Please elaborate on this mod, as I am not getting the jist from the photos alone.
Is the Velcro having to do with the lock stem assembly, the lock actuator, or what?

ETA: I found the YouTube video and now understand. Seems like a good mod for rattling lock stems. I don't have that particular issue---the lock actuators themselves are noisy in my ride as they operate.
Thanks

Im assuming this mod is to quiet them as they lock? mine sounds like little .22 gun shot when i lock them or i put the car in drive

Have you considered removing the pin stripe?

What are you trying to say?!!



I've thought about it. I'm on the fence if I like it. Is it easy to remove?

I can't quite tell, but since the Velcro is on the back side of the lock stem assembly, I guess it must quiet that action. I may experiment this weekend since it's quick & easy to test.

Sorry missed your earlier post. It stops annoying rattles when driving.

I changed the front diff, rear diff and xfer fluids. Everything looked normal.

I'm driving from VA to MT and back. Gotta make sure all is well! What's your over/under on a trouble free trip? ;-)

Uhhgggg I have list to fix before the week ends for my MT trip.

A/C is freezing over.

- It was low on coolant, no leaks detected when properly pressurized. This slowed the freezing up.
- Filter is clean and so are the coils.
- When tested they didnt see any pressure differential pointing to a clogged orifice.
- I have a new low pressure switch to install soon. I hope this helps. This is a common failure

Both rear door actuators have died. Got some Dorman replacements.

Cruise control is dead. Great. I really want this for a road trip. The stop lamp switch is known to go out and cause this prob.

I got a new spare. $111 mounted and balanced. Who knows what part of china this was made in. Don't care!

Chains! I got these because of freak storms. Actually more to scare the wife. I love messing with her.

Both rear door actuators replaced and working great!

Here is a picture where I put velcro to stop door rattles.

Now I know you're joking. You don't need chains after driving in alaska.
We did get a ton of snow here over winter, like what it use to be back in the 90s.

I was there in the 90s ;-) Great times!

Yeah its a joke to mess with my wife.

I replaced the low pressure ac switch. Its hard to tell if it's helping. Ambient air was 65f, I set the ac to as cold as possible with lowest fan setting. I could just get it to start icing over. It's a stupid test and might cause any ac to freeze a bit.

Old out!

I fixed the cruise control. I had to replace the brake lamp switch. This had me worried for my big trip.

 

[tgui]

AC Fixed. You'll never guess....

It was my new HVAC controls. I'm not a pro. Supposedly new HVAC controls need a GM tech programmer to setup or it causes all sorts of issues like freezing up.

I'll deal with the old controls for a while.

Good news is that I have no leaks, new low pressure switch, new orifice and so forth.

My, my, my it's been awhile since I checked in on this thread! Best of luck on the cross country trip! I need to get a build/resto thread going on my wife's Escalade since your build threads inspire as always!
