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.

Not every job is a big horsepower build, but every repair makes a difference. 👊

This 2008 GMC Yukon Denali came in with a loud whining noise at highway speeds and a clunk when taking off from a stop.

✅ New front differential
✅ New front differential mounting bushings

The result? No more whining, no more clunking, and this Denali is back to driving smooth and quiet like it should.

We enjoy the performance builds, but keeping our customers’ daily drivers reliable is just as important.

👀 Also… peep the American Racing Headers in the foreground. Any guesses what they’re going on? Stay tuned… we’ve got another fun build coming soon! 🔥

This ‘99 2500 definitely tested our patience, but it’s finally coming together. 💪

It came in for a cam kit and quickly turned into one of those “while we’re in there” builds.

✔️ Found water in the fuel tank, so we drained it, installed a new fuel pump, fuel filter, and a set of FIC injectors.

✔️ Moved on to the cam swap and discovered the factory iron heads wouldn’t work with the valve springs for this setup. No shortcuts here, so we tracked down a set of aluminum heads.

✔️ Since everything was apart, we upgraded it with a fresh set of BTR lifters.

✔️ Finished it off with a custom-ground EPS cam.

This truck fought us every step of the way, but that’s part of building them right. Next stop… a Whipple supercharger. 😈 Stay tuned. 🚀

Another one headed out the door! 🔥

This clean C6 Corvette came in for some well deserved upgrades:

✅ TSP 228 cam
✅ Trunnion upgrade
✅ Custom in house tuning

The result? A completely different car with a nasty idle, stronger pull throughout the RPM range, and drivability dialed in just the way it should be.

Nothing beats hearing one of these LS engines come to life after a cam swap. Thanks for trusting us with your build!

This super clean, well-maintained 2005 Silverado 1500 came in for a serious performance refresh. 🔥

We installed one of our custom-ground EPS truck cams, paired with BTR .660 dual valve springs, hardened pushrods, BTR lifters, and a fresh oil pump to give this setup the reliability and performance it deserves. We also added a Tru-Cool 40K transmission cooler to help keep temperatures in check when the fun starts.

After the hardware was buttoned up, we dialed everything in with our in-house custom tuning for maximum drivability and performance.

The upgrades aren’t stopping there. The customer also ordered a custom-built Circle D stall converter that’s currently being built, and we can’t wait to get it installed and see what this combination really does. Stay tuned for updates on this one. 👊💪

Finished up our first cammed L8T build this week.

2020 Silverado 2500HD 6.6L Gas

• BTR 220 Camshaft
• BTR Springs
• BTR Pushrods
• Custom HP Tuners Calibration

The 6.6 gas trucks are proving to be a solid performance platform. Excellent drivability, strong power gains, and a sound that speaks for itself.

• 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

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.
