I have an S&B and many have 3rd party CAIs that flow way better and they don't require the flash.  I'm not 100% on what all the flash includes but feel it's more related to the air filter change interval than A/F mixtures which the truck can easily adapt to.

That’s exactly my thought I’ve had plenty of intakes and never had to flash don’t get why this one would be different but for 107 dollars I think is worth the risk

You'd have to do a bit of digging but you won't be the first to install this without the flash.

I installed my GM intake myself and drove it a week before getting it flashed at the dealer.  No codes, messages or errors in my case.

Same here. Drove for several days before getting the flash. No noticeable difference either way.

I just had this GM intake installed on my 2020 5.3L by the dealer, and the flash was completed as part of the install.  The flash has nothing to do with the replace-air-filter interval warning on the DIC as the installation instructions tell the tech to disable that function in the DIC as it's not compatible with the non-standard air filter that comes with the CAI.  On other forums there is much speculation as to the actual purpose of the reflash, but it's all guessing - an adjustment for a difference in airflow (I assume at sea level), to compensate for a difference in the new location of the MAF sensor in relation to the air box, etc., and other ideas.  Who knows the real reason besides some GM tech in Detroit. As to whether or not you can get by without the reflash, one of the firsts posts on this forum is someone who installed it and encountered some issues after about a week (see below).  However, I will say this, the truck feels more responsive after the intake was installed.  I doubt that this is because of the negligible increase in horsepower and/or torque, but I believe it's more attributable to the reflash.  But this is all seat-of-the-pants sensing, and my butt is not calibrated, so I might very well be imagining things.

      Gas Prices

      By PhilB · Posted

      Did you even read this article?   Even the title of the article says "U.S.-Iran Deal Doesn’t Mean a Swift Return of Oil and Gas Flows"   Remember, crude oil prices are based on FUTURE purchases by the oil companies.  Gas prices are based on FUTURE purchases by the station.  This article stated that many of the oil producing nations have to restart their processes to get the oil produced.  Then the oil has to be shipped to wherever.  And it doesn't get there overnight.  And most of that oil is not coming here. Check out this site:  https://afdc.energy.gov/data/10621   A graph will pop up to show where the US imports their oil from.  Notice that there isn't a lot of import from OPEC and Iraq.  Most of the US import comes from Canada. The US oil produces are selling their oil on the open market, which is why the US fuel costs went up.  So you're correct, the US oil companies are going to slow walk the price downward.

      Stabilitrak conversion to Z71

      By teamjnz · Posted

      I just purchased a 2004 Tahoe with 148,******. I used to have a 2006 Suburban that had the push button Auto 4X, 2Hi, 4Hi and 4Lo. When checking out this truck I noticed it had push button but didn’t focus on it. After the purchase when driving home, this is when I noticed it was different and after a little research found out it has the AWD stabilitrak system. I don’t live in an area that requires AWD. I bought the truck to start a new adventure in life with off roading, now that the kids are all grown up. I purchased the truck knowing it didn’t have the G80 rearend but plan on re-gearing to drive on 33s or 35s and upgrade with a rear locker and still be able to tow when needed. Blah Blah Blah Anyway I know am thinking about converting the stabilitrak  to Z71. I know I will have to replace the transfer case. So now the information gathering stage is happening to see if it is worth it. Is the front AWD stabilitrak differential different when compared to a non-AWD front diff? Will I need a completely different front differential or can it be converted? What else should I be considering? I did see something in a video for GMT900 platform with removing the ABS fuse that disables the stabilitrak and turns the truck into a 2 wheel drive. Would that work in the GMT800 platform?
