You can't calibrate/alter these computers so a different throttle body can't be used.

 

I think the intake design is cool and looks good but why wouldn't GM engineers just call you up if you somehow gained up to 2mpg that they couldn't?

This.  I call complete BS on the MPG/HP gain claims.  "Up to" leaves a lot of wiggle room to blame the user when it doesn't happen.

Coming from the flipping the air cleaner lid to open air cleaner later cowl induction to cold air on fuel injection engines. I realized one thing recently. No truck manufacturer is going to leave that much HP on the table. Especially when one of the first things in their ads are HP-TQ ratings. All they have to do is increase the snorkel and the fender opening if more air is needed. How are you going to increase fuel mileage if you’re engine can pull enough air to hit 5K RPMs and you’re cruising RPMs much lower. Yea I bought it for many years. Buy truck, change exhaust, check, cold air intake, check, foolish, check. Now if you want noise, different.

I've said that about any "cai".  GM didn't spend all that money designing a 375hp (5.3) motor for example,  only to throw an intake system together that loses 20 hp and lowers mileage accordingly.

The Roto-fab CAI for the 6th gen Camaro received the same kind of skepticism, but after thousands of units sold and over a hundred independent dyno tests, it is now recognized worldwide to be the best CAI available for 6th gen Camaro. We expect the same to happen with the Silverado/Sierra.

Are the gains advertised for a 5.3 or 6.2? 

5.3L

Tell me why your system is better at $499.95 than K&N at $435.99 that claims higher gains?

That’s a good question.  We haven’t tested our competitors’ intake system, so I will focus more on what we have learned during our testing and development of this intake system as well as others. First, here are some things to consider when comparing and/or evaluating dyno numbers:

 

1)      Dyno numbers vary

2)      “Back to back” testing without the vehicle thoroughly learning a new system is useless information

3)      Manufacturer’s claims along with results from as many sources as possible should be used to evaluate a system.

 

The first point will always be true because the large number of variables involved.

 

The second point is one most people don’t understand. Straight “back to back” testing of an intake either on a dyno or at the track is not an accurate way to test. The testing is not accurate until after the engine management system has “learned” the intake.

 

The third and most important point is a tough one since this particular vehicle is relatively new to the market. With the 2016+ Camaro SS as well as the ZL1, we don’t have the highest horsepower claims among aftermarket air intake manufacturers.  However, after time on the market and countless test results from many of the best tuners in the country and abroad, it’s very safe to say we have the best performing intake available for those applications. In fact, this same principle holds true with virtually every intake we offer. We don’t have the highest horsepower claims in any market. Nonetheless, when the systems have been on the market for a year or two and all the new hype settles, our intake systems are recognized by most as the top performing intake available for the application. We know how our new Silverado/Sierra 1500 intake performs and we fully expect the same conclusion to be drawn with this system.

 

Your question was in regards to horsepower gains. In addition to performance, our system is constructed using high quality components, sounds great, looks very clean under the hood and fits the truck as it should. We also offer great customer service and we are here if you want to talk to us-both before and after the sale.

If you would be kind enough to send me one I will provide detailed daily feedback on it is performing!!!!!!!!!

I will be providing feedback as my order goes in on Monday [emoji16]. I have their system in my Camaro. City driving I didn’t really see any real change in gas mileage (don’t care). Highway comparing two long trips (1 being the same route Indy to Bowling Green), with the roto-fab I seen a 1 mpg gain (23 to 24 mpg).

Can’t wait to get mine [emoji1360]

A group buy would have been nice of you to offer but please don’t now, unless I would be entitled to a partial refund. ?

    • Yea a fluid change is in order here. Honestly, your transmission didn’t even get hot. During the summer in stop and go traffic I’ve seen my 8l80 get up to 216 and it was still shifting smoothly. 
    • I'd change the fluid and start there.   198F is nothing for the 8L90.  They typically operate 180-200F stock.  
    • Looking for help!   2019 GMC Sierra 1500 - 5.3l 4x4 8l90 61k miles - truck is in Arizona, was over 110 outside on Monday when this whole situation transpired. Never had any major issues with transmission until this point:   Truck sat outside my construction office for approx 1 hour idling before I realized, ran around the job site wrapping some things up for the day and then left. Went to get food and sat in the drive through for approx 30 minutes idling. As soon as I pull out of the drive through and onto the main road, rear tires lock up and feels like transmission fell out of the truck. Shifted to park, shut the truck off and tried again, same thing happened. Was able to reverse into parking lot (truck slammed into reverse). Let the truck sit turned off for 10 minutes before trying again, but it continued to happen. Towed truck back to my house. Highest the trans temps reached was 198.   Friday, after work I start looking into the situation. Truck sat in my driveway untouched all week. Truck is now driving like normal, transmission doesn’t get over 185 degrees when trying to heat it up. Got up to 60 multiples times with no issues, no issues accelerating, only down shifted hard into first one time at 185 degrees. Does anyone have any insight? Never through a code or a check engine light. Truck has never been used to tow either. No transmission services at this point.
    • Atlas won.   I know better, but I did it anyway. I took a compressed air line with a chuck and rubber tip and jammed it in the open EGR port. The port was clear as far as I could see, and as far as I could poke with a flexible wire, but that doesn't mean it's not clogged.   Compressed air blew back at me along with a cloud of black. Oops. I didn't have the rubber tip seated in there all the way. Jammed it up in there some more and squeezed the chuck. PSI was set to 120. Poof! It blew back at me again. Third time...pfffffttssssssspffffffsssfffffff, face full of carbon, and then, kind of a thud..and the air stopped spraying back at me. It was now exiting the exhaust with a low shhhhhh sound as it flowed through the pipe. Something broke free. I pressurized the port again, and air flowed.   Made my day.   Long story short on this problem, it's fixed. Something was really blocking the EGR passages down low, and compressed air blew it apart. I don't recommend this as who knows what debris was sent where. But it's allowed me to move forward, mentally, and onto the next problems I need to get this little S-Blazer going down the road properly again.
