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

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?

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 --

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?

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.
