First time in over a month I actually used my XL - had to transport some props I made for my daughter's dance studio, and it got dirty.

Otherwise, what do you guys think about the Sierra wheels with the 275/65/20 (34.1" x 11") Falken Wildpeak AT 1's? To me, the 3" keys, Z71springs and spacers lift it just enough, makes the wheels and tires look so much better in proportion.

Imo looks good. Has that beefy look to it.

did some tuning last night, flashed new file today, i disabled all traction control BS, tuned up shift pressure and shift times in the tranny and changed the pe file some, made it tad leaner up top and made its tp% enable 50% vs stock 90%., feels so much better with a little bump into each gear now, throttle seems more responsive too.

next is some maf tuning being the o2 sensors look really good on the hpt scan.

Just went to the dealership. They are impressed with my denali, which made me happy, but pointed out my rear autoride is completely shot, to included the compressor. And it wouldn't hurt to change a gasket for the oil lines that go in right above the filter.

He was also extremely confused as to why I wasn't complaining about water getting in the truck with the roof racks removed haha good guy. He showed me all this stuff on the vehicle that he would fix and showed me how to do a lot of it.

Why would you lean it out unless you want to burn a hole in a piston. There's quite a few people who have blown their engines and trannies tuning. I hope you know what you're doing. Good luck.

.200 is hardly a lot. and im not new to tuning. just new to hp tuners, so im going slow with some hand holding from others who got a good grip on the HP program.

PE mode is wot only. your on the maf till that point, then it runs off the pe file. pe files are rich on stock tunes generally. if you have a wideband you can adjust it with 100% reliability. thats likely next on the list of crap ill buy.

Gotta let us know how much of a difference there is with the new shocks. Are these the 4600 or 5100? I forgot.

5100, so far it took away that tire sound when you hit a large bump or pot hole, over all rides nice. ill update in a week or so after i get some more drive time on em. drove home 5 miles and parked it.
