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.
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!
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.
Turn the volume up and let us know what you think. 🔊👇

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.
