- PCM / ECM Bench Tuning: Fast mail-order bench tuning for P01, P59, E38, and E67 controllers via HP Tuners—including VATS deletes, segment swaps, DTC cleanup, fan triggers, and speedo calibration.
- Custom Relay & Wiring Kits: Heavy-duty dual fan relay setups, fuel pump harnesses, and power distribution modules.
- Swap Technical Support: Direct technical expertise to ensure your engine fires up on the first turn of the key.
Built Right. Tuned Right. Performance That Lasts.
Every controller processed through our shop undergoes full 14V bench-rig verification before return shipping. Whether you are building a weekend cruiser, a daily driver swap, or dedicated track machine, we deliver the technical precision your build deserves.
