Gwatney Performance Innovation can perform nearly every performance modification imaginable to a wide variety of vehicles. Custom ground camshafts have become a mainstay at GPI – especially for the LSx motor platform. We often venture into Supercharged and Nitrous projects – and bring the total package together with a custom tune using our own in-house DYNO.

Boost makes power. Oil v***r makes problems 🛢️

That’s why we trust Mighty Mouse Solutions products on our builds.

From catch cans to crankcase ventilation setups, these systems help control blow-by, keep oil where it belongs, and support cleaner, more reliable performance under boost and high RPM.
