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

[Denaliz]

Operation: Getting the ole girls swagger back, is underway.

started a couple of months ago refreshing all interior panels and clip retainers. Now I’m finishing up the weatherstripping and door seals.

I replaced all door seals a few months ago because I got tired of looking at the ripped up bottoms where people step in and out of the vehicle now I’m replacing all four door lower seals. Mine have been gashed and torn from 10 years of service.

I also got my parts in to replace the front oem air struts and hardware. I have pair of ac delco 580-373 air struts for my z55 front suspension to get installed. I decided recently to go ahead and replace the entire front coil over strut setup with parts and new coil springs that I’m on the hunt for.

im going to have a 2/3 drop done at the same time of the install. Just working out the details on front spring part numbers. I did the rear shocks last summer when I did the Eibach swaybars.

plan is to do a cam and headers TSP package as well. Just ironing out the details and total costs vs supercharger.

this should be a fun 6 months coming up for me.

Trico Force 25220, cheap and nice, beats the hell out of paying $30-40 for the bosch, the trico's are beyond there 2nd season and still like new, the bosch I had to replace every season.

More Information for TRICO 25220

Got these today. they are a nice solid blade. much better than the overpriced crap I got a Walfart! Thanks for the info and suggestion.

Are misfire counts stored in the pcm? I ask because I want to watch for them with my tech2 but they are gone within 30 seconds of starting the truck. I didn't notice this before the plug and wire change. I want to set the count to zero tonight and start it cold tomorrow and them look at which one it might be. Then to see if it follows a plug or wire.

Might be in my head too.

You should be able to graph them at least. @Tonyrodz did, didn't he?

 

[George B]

no misfires stored or otherwise. It is running on 8% ethanol now so and I have always noted rougher operation on lower E%. If it ain’t broke…

TUNE IT!

I was able to get to these screens with the Tech2 --

Me too and did graph them on our envoy but there were none to graph on the burb.

Just throwing this out there, if anyone replaces their rear rotors and is going to trash the old ones I would like one for some tests and will pay for shipping if you send it to me, flat-rate USPS is probably the easiest, and cheapest.

Must be a 13.5" rear NNBS rotor and I don't really care how worn out it is.

NBS rear rotors are bigger than NNBS, FYI.

They are?

 

[Rocket Man]

They are?

I thought so, this has been discussed when we were doing the NNBS front swap onto the NBS. People were saying the NBS had 13” rears, 12” fronts and the NNBS had 12” rears and 13” fronts. I never checked when I pulled the originals off my 08 Silvy.

My '10 PPV has 13.5 rotors on the back; confirmed that over the weekend while exploring some options

Are they single or dual piston? I know my NBS rears were dual.

Single, that was the reason for my inquiry. I'd like to upgrade the rear calipers

 

[gooffeyguy]

My 2001 rear calipers are dual piston.

My 2012 rear calipers are single piston.

The 2001 calipers are shorter in length then the 2012 caliper though.

How do I check my ethanol % with my Tech 2?

My 1 tank of E85 has dropped my MPG like 30%.

I checked my Ethanol level and it read 60%

 

[1BADI5]

Yeah my ethanol sensor in my truck is stuck........reads 23% at all times

I heard him say you'll get your meat back after 90% of the population is vaccinated

It’s weird to me that the NNBS rears have a bigger rotor than the NBS yet they’re single piston while the NBS are dual piston with smaller rotors. It seems to me the NBS dual piston would actually be better even though they have smaller rotors. Thoughts?

I don't know if they would or not. I do know that on my 2001 I go through rear brake pads quicker than the front pads. I always thought the brake bias should be higher in the front than rear, but it seems to be opposite on it. Maybe that's why they changed the caliper style on the NNBS

She was speechless, figuratively and literally! That was the part of the video right before she was holding her stomach.

This is the part that makes me unable to wait for her to start driving. The thought of paying insurance kills it, though! I'm hoping she'll accompany me under the Tahoe for the oil change coming up in 600 miles. She's such a bookworm- maybe I can slip in some custom car mags for her to read. Maybe we can nerd out on sound waves and calculating enclosure volumes for the Tahoe's sub system.

Tell her you need help with some math. Crunching numbers for the mpg or some assistance getting the tuning dialed in. Kids always like helping when they can teach something new to the older generation.

Not trying to pry, but have any of you guys with kids (in their teens) thought about or looked into building their credit? Credit score, and the fair issac corporation (fico) score weigh heavily in the cost of an insurance premium. Most drivers under 25 don’t good or any credit, but their adjuster never bothers to tell them that they can lower their premium by having a better credit score.

My 02’ was different than your 01’. Mine had dual pistons and the rotors were smaller than my 11’. I never compared the height of the OEM rotors, but I know the aftermarket are thicker and taller.
