I have recently put a k&n drop in filter in. Just wondering if i should disconnect the battery to let the computer compensate for the extra air or just let it learn on its own.

Although not necessary, disconnecting the battery isn't a bad idea. I disconnected mine for about 20 minutes or so, then I reconnected it and started the truck and let it run for a few minutes to let it relearn everything. The only bad part is reprogramming your radio presets. :D

I agree with Roofer 100%.  It's easier for your computer to compensate from it's stock settings rather than it's "learned" settings.  (That's my opinion).

 

I have always made it a practice if I'm doing anything under the hood other than filling the washer or checking the oil to pull the Neg cable off the battery.  This way I don't run the chance of shorting something out and freaking out a bunch of electronics.

 

Although the K&N is a "drop-in" and won't require much wrenching...  I'd disconnect the battery and reconnect it when you're done.

What if I have had my codes updated at the dealership. wont disconnecting the battery, just erase those codes.

I don't know for sure but I don't think you'll lose any new updates.  I believe those are flashed into the memory, and take place of the current coding in the system.

 

It's kinda like when you get your critical updates from "Microsoft" online.  Even if your computer battery is dead, the updates are still there...  The computer battery maintains non-critical functions, like date and time.

      Acceptably cheap tires?

      By Atlas · Posted

      Which one, the AT or AS?   Starfire is made by Cooper/Goodyear but at $85/tire I'd think I'd need to level-set my expectations that they may not even be round 😉 But you're saying they're decent?   I'm already into this thing $1506 in parts, fluids, etc. Totaled all my receipts today. $250 of that was replacing an EGR and MAP sensor that were probably fine, but I'm not going to return the parts since they've been installed. I'm cheap, but not that cheap. I use it, I keep it!   I may or may not make money if I sell the truck at this point, but, that wasn't really the point. And if I billed my time, I'd be hosed for real. My thought on the tires is I "might" put 1,000 miles on before selling it. I just don't want to put absolute junk on it, that doesn't do anyone any good. If the Solus solidly isn't junk, I'll definitely consider them.

      Is your l8t engine bay super dusty?

      I leave mine as is. I'm always a trip away from riding on unpaved roads. Dealer can clean it when they prep it after I trade it in for another new truck.

      I have these on two vehicles and love them. Pepper is one of them 😉

      4WD. Far as I know it came stock with P's and not LT's. Definitely planning to put P's on it, but stock is a 109 XL load rating so I should probably stick within that guideline.   No rebates on anything I can see at the moment. Discount Tire is offering $50 off, but Pep Boys is very competitive on price, and also carries all the off-brand stuff. Les Schwab always wants an arm/leg, but they do good work.   It still has the original spare. Goodyear Wrangler RT/S, thing looks like a tractor tire LOL!! How times have changed.

      2020 Sierra 2500 windows rolling down

      By JohnRoy · Posted

      2020 Sierra 2500 HD (base model) gas engine 4wd.    All 4 windows roll down on their own. Happens somewhat randomly after stop and engine off - when engine turned off, when walking away from vehicle before or after locks activated. Pulled the window fuse F14 Instrument Panel Fuse Block Right; the driver's side still activates from driver's side door panel; passenger and back seat windows activate from local switches on their doors but not from driver's side group of switches. Power mirrors don't activate with fuse removed either (same fuse for both circuits). Problem not solved.    How can they even activate with fuse removed but they are all still opening and can control from each door?  When they open on their own, I can shut them from the switch in each door, but they don't stay closed.    Seems to be activated somehow with key fob; something bumping the key fob in my pocket or just handling - removed key fob and took it far enough away and now the windows stay closed. Replaced key fob batty just in case, no change.    Sounds like some kind of wiring short or maybe electronics. Dealer will first replace electronic control module without checking anything else and I anticipate problem will still exist since their troubleshooting skills are limited to "do whatever the computer says".  In any case, keyfob seems to be activating the circuitry.    Surely I'm not the only one with this issue, but I can't find anything related on the site. What do yall think?   JohnRoy
