I used the disabler for a while and got tired of it. I ended up doing the Crazed Performance VLOM mod. Not a complete AFM DOD delete, but it stops the 4 cyl mode. Called the VLOM mod. It disables the mechanics of the AFM and programs out the ECU mode.
If I had to do it, I would get a Diablo where you can get better transmission shifting and maybe a little engine efficiency and throttle tip in via programming instead of the foolers whether they are made here or not.
Search the forum. Several threads about AFM. Basically you are still at risk for AFM failure unless you delete the AFM components.
So you might as well wait until it fails then remove it, I've got 250,000 km (155,000 mi) on my 6.2 Sierra, same engine as my Corvette, and still running strong.

Don't know. How much is it to get a new engine vs how much to pay for the cam today and be done with it? If you are a "lifer", sure. If you are going to dump it at some point, relatively soon, the equation is more murky.
Do you need a new engine if the AFM fails, or just the cam and lifters and related parts? I don't know.
Case by case basis my friend. It's a roll of the dice if it takes anything else out. Metal all over the place as well. My buddy did HC on his LT4 Z06 3k miles and one of the AFM lifters already spun in the borrowed and w as going flat. Never made a sound. They're junk. Activating and deactivating? What could go wrong?

Not the same engine, they may both be 6.2L but the pickup trucks do not get the LT1 in your Corvette. They do have differences.
Same as in GEN V 'L' series engine, same block, VVT, DI and AFM, heads (basic casting anyhow) 420 hp in the Sierra, 460 in the vette, but yes different in how they are tuned.
My 2019 Z51 stingray is automatic, so it goes from 8 to 4 cylinder. Wondering weather to use a dfm disabled. Looking at BOOST because its made in USA
I haven't checked the price of a Boost device but I'm using a MaxCylinder AFM disabler on my C7 LT1 and it works very well. Price on Amazon is $180. Made in USA.
No matter which way you disable the AFM your engine will stand a better chance of not having a lifter failure.
GM had a video out on the operation of the AFM system and said a lot of failures occur durning the transition phase, V8 to V4 and back, due to miss timing of the locking pins.

Words like "better" and "a lot" really don't say much. If they can say "50% of failures are happening during the transition phase"we have something to consider.

It would be nice if they would quantify the improvement from electronically disabling AFM without actually changing the parts.
But they didn't have to say anything at all, so we should appreciate that.
You sound like the kind of guy who would complain if they gave you a new C8 but the gas tank was only half full.

I'm going to go against the grain and disagree. As someone in sales told me, "Yes" is the best answer, "No" is not as good and "Maybe" is the worst answer. I love specifics and hate vague answers that are designed to obfuscate. I'd rather have no answers. The vague answer is to placate you into thinking they are being nice and are aware of the problem and let your mind wander into thinking a fix might be around the corner. So please, be specific or don't bother to tell me vague crap and make me guess all day long and waste my time and energy.

They say a lot to me.
By design, it will work with most people. Like any scam, it sounds great if you don't ask too many questions as to how they came to know this, that or the other. Kinda like people only look at the bottom right hand of the quote without asking the details.
Whose scamming who? What are your credentials to make you a believable authority on this, or is this just your opinion?
Everybody is entitled to an opinion, others will decide if it has credible.

I'm not the authority on whether it is better or not. Certainly not the authority on "better" since adjectives aren't easy to quantify. They are. It is their product and their research, if any was done. IF you can ask me my credentials, perhaps you can also ask them for their "research" and we can certainly try to digest it. With quantifiable data, it might, a guess on my part, cut down the need for opinions.
