A super clean 2010 Camaro SS hit the shop for some serious sound and power upgrades! 🏎️💨
We installed Stainless Works headers and a Borla ATAK exhaust system, topped off with a custom Heath Besner tune. The results? A solid 382 whp and 395 wtq—all on a completely stock engine and intake. Not too bad if you ask me!

Doing headers on a 2025 Ford F-150 is an absolute pain in the ass—there’s zero room to work and every bolt fights you. 🛠️ But man, the results speak for themselves!

2025 Ford F-150 Roush Supercharged.This truck arrived at our shop baseline-testing at just 550 whp. To unlock its true potential, we installed a new pulley, high-flow injectors, long-tube headers, and a methanol injection kit. After a precise custom calibration by Heath Besner, the F-150 put down an impressive 774 whp at 13 psi running on 91 pump gas. Despite the massive power gains, OEM-level drivability and smooth street manners were fully maintained

Customer brought his truck in for a supercharger install after getting it cammed by another shop. Look at what we found: broken bolts on the intake manifold, a missing cap on the fuel lobe, and the worst part—the AFM oil galleries are completely missing the plugs! 🤦‍♂️ This is exactly why you don't let just anyone cam these trucks. Quality work isn't cheap, and cheap work isn't quality. You get what you pay for when you try to save a few bucks! 🛑🛠️

Beautiful 1968 Corvette came in for a oil pump replacement on a swapped Ls3 so we went ahead and installed a high pressure oil pump along with a muscle car oil pan from Holley do to having a knock off oil pan that wasn’t sealing the oil pick up tube correctly and a couple more issues we found along the way do to swap not being done professionally.
