Watson Performance LLC

Watson Performance LLC Specializing in 1997+ LS based GM Trucks/SUV/Cars performance modifications & tuning I was performing complete cam upgrades on GM trucks at the young age of 16.

I began this business to pursue my passion for the automotive world, more specifically the performance side. My love started years ago with atvs, and the passion soon evolved into cars and trucks. Over the next years I went on to get a degree in automotive technology as well as several ASE certifications...I have studied GM tuning and the use of HP Tuners software for over 10 years, and I continue

to stay on top of the ever evolving world of tuning and performance capabilities of LS base engines.

Fresh service and dialed in 🔥

This 2018 Silverado stopped by for a full maintenance package plus custom tuning:

• Front & rear differential service with Amsoil Severe Gear 75W-90
• Amsoil Signature Series oil & filter change
• New spark plugs & wires
• Replaced 1 coil pack
• Tire rotation
• Lower oil pan reseal
• Custom HP Tuners calibration

Not only is this truck serviced and reliable, but it’s running smoother, shifting better, and performing the way it should 👌

From maintenance and repairs to full performance builds & ECM/TCM calibration — we’ve got you covered.

This 2008 GM 1500 came in after the factory G80 decided to self-destruct in spectacular fashion. 💀😂

The good ol’ “Gov Bomb” finally earned its nickname and turned the rear end into a metal recycling program.

So we rebuilt this one the RIGHT way:
✔️ New ring & pinion
✔️ Yukon DuraGrip locker
✔️ Master bearing/install kit
✔️ New brake shoes & drums
✔️ All new brake hardware

No patch jobs. No reused worn-out junk. Just a solid rear end setup built to live. 😮‍💨

Now this truck is back to putting power down like it should instead of sounding like a toolbox in a dryer.

2014 Silverado came in misfiring like it just lost a fight. 💀

After some diagnostics we found the injector had shorted out from coolant dripping off the heater hose onto it over time. Peak GM engineering right there. 😂

Swapped the injector out and got this one back up and running right again.

This is why diagnostics matter.
Would’ve been easy for somebody to throw plugs, coils, and random parts at it before actually finding the problem.

The luxury family SUV… with a factory lifter failure waiting to happen 😬

So we fixed that too.

This 2016 Yukon Denali 6.2 just got hooked up with a:
🔥 BTR Stock AFM Delete Cam Kit
🔥 Full AFM/DOD Delete
🔥 Custom Calibration

This setup is PERFECT for customers that want reliability, better drivability, and more sound/power without going with a huge chop cam.

No more AFM junk.
No more wondering when the lifters are gonna scatter.
Just a strong running 6.2 that drives smooth, sounds better, and pulls harder than stock 👌

These 6.2 Denalis wake up BIG with the right setup.

GM really gave these trucks 355 horsepower and the personality of a microwave from the factory 💀

So we fixed it.

This 2020 Silverado 5.3 just left Watson Performance with:
🔥 BTR Stage 2 Truck Cam
🔥 AFM/DOD Delete
🔥 ECM Unlock
🔥 Custom Calibration

And the 10-speed transmission tuning completely changed the way this truck drives 👌
No more lazy, confused factory shifting. It now shifts quick, firm, and actually stays in the right gear when you get on it.

Now it shakes the parking lot at idle, snaps your neck when you hit the throttle, and finally sounds like a real V8 should 😤

No more lifter time bomb.
No more sewing machine exhaust note.
Just chop, torque, and bad decisions.

This thing went from HOA-approved to “the neighbors are definitely talking” REAL fast 😂

🎥 Crank the volume up and enjoy the idle.

We’ve been so busy at the shop lately we forgot social media even existed… 😅
Cars been rolling in and out faster than 4L60s fail.

But we did manage to snag a pic of this 2008 Suburban we just finished up — customer came to us after going through THREE 4L60Es. Yeah… THREE.

So we fixed the problem the right way:
👉 4L80E conversion

No more bandaids. No more “maybe this one will last.”
Just a transmission that actually belongs behind a truck.

If your ride is on its 2nd… 3rd… or “I lost count” 4L60 — you already know what time it is.

Stop wasting money. Do it once, do it right.

Another one back from the dead 🔧💀➡️🔥

2019 Dodge Charger S**t Pack 6.4 came in hurting… wiped a lifter, took the cam out with it, and even managed to spin the crankshaft balancer for good measure. Not exactly a light cough.

Got it straightened out with a BTR 224 cam kit, MDS delete, and fresh tuning.

Now it’s running stronger than ever and sounds absolutely nasty 😤

From barely hanging on… to turning heads every time it fires up.

This one left better than it ever was 💪

💣 AFM said “I quit”… we said “good, stay gone” 💣

This 2018 GMC Sierra 5.3 came in sounding like a bucket of bolts after an AFM lifter absolutely nuked itself and wiped the cam with it 💀

GM really said “let’s save fuel” and accidentally created one of the most reliable ways to destroy a 5.3 😅

So we did what we always do…
we fixed it the RIGHT way 👇

🔥 BTR Stage 2 Truck Cam
🔥 FULL AFM/DOD DELETE — permanently fired
🔥 Fresh valvetrain (because the old one chose violence)
🔥 ECM Calibration — dialed in in-house

Now?
This thing went from barely surviving… to straight up disrespectful 😤

✔️ Choppy idle
✔️ Strong pull
✔️ Zero AFM nonsense

🎥 Turn the volume ALL the way up… that idle is nasty 😈

If your 5.3 is ticking, misfiring, or “acting a little funny”…
that ain’t a phase — it’s a warning.

👉 Fix it now or pay for it later. Your choice.

A few of our recent google reviews—Nothing means more to us than hearing from happy customers.
We truly appreciate everyone who trusts Watson Performance with their builds — whether it’s a simple tune or a full cam swap. Our goal has always been to give every customer honest advice, quality work, and results they can feel the moment they hit the throttle.
Thank you to everyone who has taken the time to leave us a review and support our small business. We wouldn’t be here without y’all.

Sunday grind never stops.

Knocked out a BTR Stage 2 V3 cam kit install on this 2006 5.3 Silverado and finished it off with a full custom tune.

Idle speaks for itself 👀🎥

At Watson Performance, we don’t just bolt parts on — we make them work together the right way.
