FAS800
800 Wheel Horsepower. Factory Drivability. No Compromise.

The Build Process
From intake to dyno sheet — every step is handled in-house at our Punta Gorda facility.
- Schedule & Drop Off
Contact FAS to confirm platform compatibility and schedule your build slot. Drop your vehicle at 6161 Riverside Dr, Punta Gorda, FL 33982.
- Baseline Dyno Pull
Your vehicle is strapped to our AWD dynamometer for a stock baseline run. Numbers are logged before a single bolt turns.
- Full Installation
Pulley swap, cooling modifications, and ECU unlock performed by FAS technicians using our validated build sheet for your specific platform.
- Custom Dyno Calibration
Full custom tune developed specifically for your car. Not an off-the-shelf file — calibrated to your vehicle's individual response curve, fuel system, and ambient conditions.
- Verification & Release
Final dyno pulls confirm 800 WHP target. Datalogs are reviewed. Your vehicle is not released until the numbers are right.
The FAS Performance Ladder
The FAS800 is built for future upgrades. Every tier uses the same baseline platform work — moving up costs less when you started right.
