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

gotta take her in for a alignment I noticed she pulls to the right a little after changing the sway bars and have them do the front pinion seal while there at it.

got an autocal during the black friday sale. shipping was super quick, i received the package after work on monday. sent BBP all of the info on tuesday and they shot back an email telling me to clean the MAF and record the data again. cleaned the MAF and re-recorded everything and sent back to them thursday. Justin emailed me the tune files on saturday. i went with disabled AFM, 87/89 and 91+ tunes and had them work on the transmission shifts. seems that actual shifting from gear to gear in the transmission is faster but it does feel like 1-2 is a little more harsh than before. black bear said the car has to get used to it for a few days so i'm going to let it ride unless it starts really acting up. pretty happy with the tune overall, the tahoe definitely has a little more pep now. havent had a ton of drive time to note any differences in mpg yet but will report back if anyone is interested.

my pants got a little tighter the first time i gave it a little extra juice on a back road and didnt have to wait for the AFM to kick off

good luck did mine 2-3 months ago, came out real nice but some of the scratches reappeared later I worked them pretty hard too, this is a just a idea I haven't done it yet myself but some super fine sandpaper might do the trick and wax it up real good afterwards

Disclaimer: doing this can really mess up paint if not carful and not all scratches will come out depending on depth.

We wet sand with 3k grit then start to buff with heavy cut down to the polish, finish with a good wax.

Not every car and every scratch gets that much attention and work though. It be a long day haha.

Do you clean it by wiping down first or clay barring before 3k sand paper and then heavy cut and working back up?

Any other grits of sand paper used?

Yea we completely wash the paint, use a claybar if needed, then start the 3k paper etc.

Nah if its bad enough for harsher grit paper we either do what we can orsend it to the body shop for paint.

Good info thx. I may give his a go on my Tahoe roof next detail just to see if it will make a difference. Maybe do a test spot to see how it goes. Thx man.
