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!

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?

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?
