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

Thanks, I'm a member there already.
I'll poke around in the C5 and C6 section.


On another note,
Looking at camshafts at TSP, they reference square port heads and cathedral port heads.
any idea what type of heads my 5.3 LMG would have?

@iamdub or @swathdiver might know

So far my plan is,
If i Wimp out: 2009 Chevrolet Tahoe 28-12560967 GM 1999-06 LM7 5.3 Stock Camshaft (texas-speed.com)
If i'm feeling a little frosty: 25-TSPLL212218 TSP Stage 2 Low Lift Cathedral Camshaft (texas-speed.com)
Feeling a wee bit more frosty: 25-TSP212218R6 TSP Stage 2 High Lift 5.3 Truck Camshaft (texas-speed.com)

5.3s use cathedral port heads, the 799 and 243 castings for the Gen IV engines.

^^ yup, you can always cross reference GM LS heads by the casting numbers

if you are using the oem remote and have the hvac set to auto it will come on, if you turn off the hvac before you shut it off the night before it should not come back on until you turn it on as far as I know, I have a aftermarket alarm system with remote start so it bypasses oem and my heat/ac will be wherever I set it last or off if turned it off.

Not sure if this is the case. It was 22* this morning when I left for work and I used the remote start before I left. When I got in and turned key it was on auto and the snowflake was on. The windshield was a bit frosty so I turned the snowflake off and hit the defrost button and turned the fan up, thus taking it out of auto mode. That's the way it was shut off after getting to work. When leaving work it was in the upper 30's and I remote started it and when I got in and turned the key the controls were back to auto with the snowflake on. DOH!

On my '08 it doesn't matter what you have the HVAC controls set at, Auto or otherwise, when you remote start.

It basis it's decision on out side temperature.

During cold weather, when in remote start mode, the blower motor will not turn on until a certain engine temperature is reached.

When you get in you may notice the blower going full blast on heat and if you had the A/C on when you last shut the truck off it will resume those settings when you turn the key to Run.

next time that happens see if the temp is then set for 74 on both sides, if it is then you are loosing a connection somewhere, just like when you disconnect the battery the hvac reset's to 74 and auto.

Nope, never have the temp set that high, only like 71 or 72.

maybe it's 72 it's one or the other 72/74, but it shouldn't be going back to auto regardless unless you press the button that would be infuriating for me especially in California where you basically have to have it set to 60 for the entire summer.

Remote start will turn the heat and seats on when cold enough even if i dont have it on when i shut the truck off. Same of its hot in the summer. My auto hasnt come on unless my battery gets unhooked or dies. Hmmm. Weird ass gm electronics haha
