    Catch Can for 2006 Tahoe 5.3

    A catch-can with a good throttle body/maf cleaning might make everything feel a bit better. Especially if that PCV hose is cracked or on it's way out. But it will definitely keep oily vapors, and ***** engine oil from getting sucked back into the intake which should keep everything clean over...

    Battery not charging

    Definitely parasitic draw or short which could be any circuit. I tried to attach two videos but there's a great one by HumbleMechanic and Junk DIY Guy. Titles are: The BEST Way TO Perform a Parasitic Draw Test and How to find a short in a modern car fast and easy (The correct way)

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

    Directly off the battery with that 4awg wire. Yes it's an 0 gauge wire. It's in the picture there, but I'm planning on redoing my power terminal as well since that little 10mm bolt doesn't inspire confidence. I just have to plan out everything since there's 3 or 4 connections I have to make and...

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

    Re-did my grounds because I noticed constant corrosion on my negative terminal and my lights started dimming. I think I solved my headlights dimming but my interior lights are still dimming with my music… I’m trying to understand how that can happen given I upgraded all my ground to 0 awg OFC...

    2 different subs, single channel?

    I have the bench seat, not the captains, so my 10" is having to push through them. My sub definitely doesn't have enough power being rated at ~300rms to fill the entirety of the truck. There's a ton of volume in the 'Burb that I think requires quite a bit of juice. The reason I want to split...

    Cold start hesitation

    Interesting, I did not know it needed 7 miles. That's quite a bit honestly. These trucks definitely seem finicky, definitely more than the GMT800's which I think had a physical sensor.

    2 different subs, single channel?

    Yeah I think I might give the Taramps 800 x2 a try. It's rated for 800watts RMS @ 2ohms and it's about the size of a dessert plate. I like to hide my subs up in my center console although I might relocate them when I redo the system to under the second row, or the original sub position that the...

    Cold start hesitation

    Yes, issue was E85 as I initially had thought. A part of me wonders if it's the sensor in our trucks. I had reached out to blackbear tuning to ask them if they could make an e85 map or tune around the issues, and they said we'd have to install a physical sensor in our trucks. Stock, it's a...

    2 different subs, single channel?

    This is more of a general question than a specific GMT900 question, but I'm looking to slightly update my sound system. Currently I have 7 speakers, non-bose. (2 tweeters, 2 x 6.5" coaxials, 2x 5.25" coaxials and 1 10" sub). I bought a 5 channel amp to power everything but it came with a bad...

    HELP - Intermittent Electrical Issues

    Sounds like an electrical issue. You could have an intermittent short to ground/short to power which is adding a ton of resistance to the system making it hard to start/keep power going through the system. In terms of the lights and back up camera staying on, I wonder if that's any aftermarket...

    Low RPMs at idle & reading around 1800 rpm at 60 mph.

    This. Could be a trans related issue as well. Honestly could be two separate issues that are unrelated. IMO here's where to start for the low idle. Firstly identify if only your idle is low. How does the vehicle accelerate? Under 25% throttle? Under 50% throttle? To redline? How does it drive...

    Low RPMs at idle & reading around 1800 rpm at 60 mph.

    02's don't control idle, they simply read the air data and report it to your computer which then makes adjustments. If you have a scan tool you can monitor the 02's to see if they're working properly. 0.0v to 1.0v is the typical operating range for a working upstream 02 sensor. Can you record...

    Dude those headlights are beautiful. How are they holding up?

    Cold start hesitation

    I tested the coolant temp sensor tonight and want to confirm everything before I potentially continue down that rabbit hole. I checked the sensor cold with the key in the on position and it read 30*C. Now keep in mind the temperature outside is 20*C, I'm not sure if that could potentially cause...
