I'm a retired mechanic so I was skeptical. Ran it on my Sierra for a month, zero issues. No more bogging down on 4 cylinders and the throttle is way more responsive. That AFM drone that was driving me nuts is gone. Let the truck sit a solid week and read 12.6v at the battery. No drain, no check engine light.
-
My lifters were getting noisy and the truck felt gutless. The shop wanted to sell me a rebuilt engine. I tried this first. Plugged it in and the power came right back. Felt like a different vehicle. Saved me thousands and it took ten seconds.
-
Asked my dealer about the engine failures at 120,000 miles. He told me if it was his truck he would install an AFM disabler. That was all I needed to hear. Pulls the trailer with plenty of power and I stopped listening for noises every morning.

Your GM Engine Is Destroying Itself Every Time You Drive
(Every 2007+ V8 Does It)
Every time you ease off on the highway, your truck quietly shuts down half its cylinders. You feel it as a shudder around 45. You feel it as that flat spot when you step on the gas. Most owners think that's just how these trucks drive.
It isn't. Every one of those switches slams a locking pin inside your lifters. Hundreds of times a trip. Thousands of times a month.
And oil changes don't stop it. Owners who ran full synthetic every 3,000 miles still lost camshafts at 70,000. It was never a maintenance problem.
When a lifter finally collapses it takes the camshaft with it. That's a full teardown. 12 to 14 hours of labor before a single part. $4,000 to $8,500, on a truck you're probably still paying for.
$89 today, or $6,000 the morning it lets go. That's the whole decision.
Same Protection, Without the Surgery
Your mechanic will offer you two ways out. A tune rewrites your ECU and leaves a footprint the dealer can read. A mechanical delete pulls the top of your engine apart. Both run $400 to $2,000+, both keep your truck for days, and neither one comes back out.
EngineKeep stops the exact same cylinder switching. It takes 10 seconds, it comes out in 2, and nothing is ever written to your computer.
Plug it in before your next drive and you'll feel it on the way to work. The shudder is gone. The hesitation is gone. And the wear stops the same day.
Real Experience From Real Drivers

Michael R., Retired Mechanic
"I spent 30 years in the trade so I was skeptical of a plug-in. Ran it on my 2018 Sierra for a month and there are zero issues. The exact opposite actually. No more bogging down on 4 cylinders and the throttle is much more responsive. That AFM drone that was driving me nuts is gone. I let the truck sit a solid week to see if it drained the battery and got 12.6v before starting. No drain, no check engine light. I recommend it 100%."

"I had my dealer do a fluid change at 120,000 miles and asked him straight about all the engine failures I'd been reading about. He told me if it was his truck he would install an AFM disabler. Coming from the dealer, that was enough for me. It pulls the trailer with plenty of power and I've stopped listening for noises every morning."

Carlos M.
"My lifters were getting noisy and the truck felt completely gutless. The shop wanted to sell me a rebuilt engine for thousands. I figured I'd try the plug first. Plugged it in and instantly felt more power and a smoother drive. Felt like a new vehicle. I'll drop $80 on dinner without thinking twice and I was gambling a $6,000 engine to save it."
Dealer-Grade Protection Without the Dealer Price
The shop charges $400 to $2,000 to stop this. EngineKeep does the same job, keeps every cylinder firing, and you fit it yourself in the time it takes to put your seatbelt on.

Will this void my warranty?
Will this void my warranty?
No. Unlike a tune or an ECU flash, nothing is rewritten. There is no electronic footprint to find. Unplug it before a service visit and your truck is exactly as it left the factory.
Do I need tools or mechanical skills to install it?
Do I need tools or mechanical skills to install it?
Not at all. It plugs directly into your OBD-II port — under the dashboard, driver's side — in about ten seconds. No tools, no wiring, no app and no complex setup to reclaim your full V8 power. As one owner put it: open it up, take it out, plug it right in.
Will leaving it plugged in drain my battery?
Will leaving it plugged in drain my battery?
No. It draws minimal power and owners have tested it — one left his truck sitting a full week, took a voltage reading before starting and got 12.6v, with no parasitic drain. You can leave it plugged in with confidence.
Does this actually prevent expensive lifter failure?
Does this actually prevent expensive lifter failure?
Yes. By keeping all cylinders active you eliminate the constant switching that causes excessive lifter wear and oil consumption. It acts like an insurance policy on your engine, preventing the shudder and the catastrophic failures that routinely cost upwards of $4,000.
Will it throw a check engine light?
Will it throw a check engine light?
No. Nothing is reprogrammed, so there is nothing for the computer to flag. Owners report no codes — and several report the opposite: their catalytic converter codes stopped coming back once the engine held V8 full time.
Why is this cheaper than the $230 brand?
Why is this cheaper than the $230 brand?
Because we sell direct — no retail markup, no distributor taking a cut. Same port, same job, same reversibility. Owners who compared both landed here, and we back ours with a 100-day guarantee and a 2-year warranty. Beware of the untested clones with no support behind them.
