GM CAI Install @ Dealership

It's hard to explain, I seemed like mine shifted funny, and then after was fine, and maybe little bit of throttle response, but could be in my head lol

You get the same sound from a $100 muffler delete.

You dont get the same sound for $100. You might get the same volume but not the same sound. With multiple different mufflers available all will give you a unique sound. Personally I have owned at least a dozen different manufacturers mufflers and they all sound different. Dont get me wrong I like the straight pipe cost but personally dont like the straight pipe sound. I also think the price for a catback is ridiculous. Performance for the money the straight pipe wins hands down. Not to say some mufflers cant give more hp gains than others due to the scavenging science behind them. But for a vehicle I spend a lot time driving I prefer to have a more refined tone vs the straight pipe. I know you weren't saying the sound is literally the same but my point is there is a reason why paying for a well engineered system (or just a muffler) has it advantages for hp and sound quality vs less expensive alternatives.

I should have said, you get as good of a sound. Yes, 5 different pipes will have 5 slightly different tones to them, but if you want a loud, deep, throaty exhaust, you don't have to spend a grand for a slightly less choked up muffler, which is all those other systems are doing. There are no crossover tubes in a muffler... If we were talking full system with headers, they yeah, we might see some differences in design that could impact performance.

When talking about catbacks, there typically isn't much in the way of performance... It's a piece of pipe that typically follows the same path as the original, because that is where the mounting points are, and then a muffler with more or less sound muffling... It's like looking at the difference in motorcycle exhausts... Full systems usually give the best gains... some more than others. With slipons, they all perform about the same. As my tuner says, a 2" hole is a 2" hole...

Straight pipe sound is hit or miss from vehicle to vehicle... I am finding that on the 2019 5.3L the muffler delete sounds as good as any catback system I have ever heard... Now, when I covered the resonator panels, it got a little louder and wasn't as smooth and had a little drone down the road, which I did not like...

If the tone of a system really appeals to you, by all means, get one. Not knocking them. But for those of us that have multiple expensive hobbies, I just don't want to spend a ton to make my truck not sound like a sewing machine... haha

I am really digging how this truck sounds with the muffler delete and resonator flaps intact.

It does come with a reflash for the maf, do not let them tell you it's not included in the price of the intake, they tried that with me. The reflash is included. There is a conformation code, and labor code in the package. Also it did make a diffrence in how my truck ran after the reflash.

Yeah, good luck convincing Koons GMC in Tysons of that fact. They refused to acknowledge the instruction from GM even throwing out the “tech has to be paid for his time” line. I ended up paying $150 for the flash as they had already done it and they refused to budge.

That sucks. I’ll find out on 12/26 if they try to charge. Did you consider telling them to “unflash” it?

Jhall124jr · December 25, 2019

Still bull, they tried the whole the tech being paid to me to, even went as far as well you dont work for free do you. If I was you I would contact chevy performance, because you paid twice for that service. The labor code in there is so they get paid.

Jhall124jr · December 25, 2019

Also one more thing, it is only billed for .3 hrs, they messed up and showed me the wrong paper work before I flipped out on the service manger.

I tried using logic (had printed out the directions with the labor code and all); I suggested they call GM for resolution; None of which resolved the issue. My SA was a little on the odd side and I don’t think really even understood the issue at hand — or maybe he just didn't GAF as he kept repeating “the tech has got to get paid, blah blah blah”.

I did not think to tell them to unflash. That would of been a good play.

If you figure out the magic words to say, please do share.

If I was you I would just call gm performance about it, I just argued with them and they got tired of me and took my charge off. I then contacted gm performance and they verified what I told them.

No surprise, yet another incompetent dealer. You should have told him you aren't paying one red cent more. The GM Performance intake includes calibration in the original purchase price. It is outlined in the instructions If he is too stupid to figure out how to process his paperwork, he can remove the kit and you can take your business to a dealer with some sense.

TBH I buy from Koons because they have the best prices in town. Ive never been under the disillusion that they have the best service around as they are a volume dealer, plain and simple.

Got mine installed today and 2 recalls taken care of. They didn't make a peep about the reprogramming fee.

I double checked and asked if they were sure it was done, they said yes. That being said, I honestly can't tell much of a difference. I would advise anyone looking to do this, to go the exhaust route for sound only. I can't tell any performance gains.

Anyone think there is any value in the intake they removed from my truck? They boxed it up and left it in the bed of my truck. I don't have a use and/or much storage area for it, so thinking about throwing it out. Do you think I could sell it for anything?

You might not have much luck selling local on craigslist, but on ebay your chances will be higher.

See this: https://www.ebay.com/itm/Silverado-Tahoe-Yukon-Air-Cleaner-Outlet-to-Intake-Tube-Duct-Hose-2014-2018/233135157429?epid=658547402&hash=item3647f030b5:g:8G4AAOSwGFZcZ4q6

That does not include the filter box, either.

I decided against the CAI. For half the money, I ordered the Airaid MIT kit.

Seen too many reviews and dyno runs of the MIT giving the same results as a full CAI box... It seems that in most cases, the restriction isn't in the box, or the filter, it is in what connects that box to the motor.

Blackbear performance published a lot of hard data from the dyno room comparing all the popular CAI's on the last gen Silverado, and the MIT was right there with them. Best bang for the buck. So that's what I ordered.

I just ordered this, Airade Junior Air Intake System they call it, part #201-782 for my 2020 Sierra 6.2L. See how it goes

You are quoting data and a post from Blackbear that was from the 2010-2013 Gm trucks and is not relative to the K2xx (2014+) and newer trucks. This is why when people make comments "that doesnt provide any extra power, just costs money and is bling" isnt always accurate.

BB did a full on test on the K2xx trucks, they tested something like 6 different full on CAI kits and yes even the Airaid MIT tube, each and every one of the CAI systems showed gains. Some of those systems (Airaid and AFE for example) showed gains nearing 20hp to the wheels.

If GM says their CAI needs a reflash, then it needs it. That is the reason they designed it along with having to keep the vehicle in compliance with the EPA and meeting the certification process.GM along with several other manufactures are all seeing the $$$ on the table that people will pay to get more performance from their vehicle, bonus is when it is the manufacture offering it and still allowing the warranty to stay in place.

OP sadly no there isnt any way to tell if the calibration was flashed from any aspect or method you have access to, the flash doesnt require the battery to be disconnected and it wont reset the radio presets as they have a memory feature now built into the infotainment system to retain the presets and the time, the time is even checked and updated from the network as soon as the vehicle gets back online.

You are going to have to take the dealer for their word on this one. Enjoy the extra power, seems GM is now offering almost 15-20 rwhp in gains for the CAI and a catback.
