Power Hungry Performance FICM Tuning 03-07 6.0L

Boost your FICM’s performance with a Power Hungry Performance software upgrade.

PHP PERFORMANCE UPGRADES
- Resolves many cold-start issues
- Usually results in more MPG
- Improves tip-in throttle response
- Results in better overall drivability from idle up through 3500 rpm
- Proven performance gains up to 100 HP
- Eliminates annoying injector post buzz
- Works with most ECM tuning

ECONOMY – Improved throttle response and economy without any significant power gains. Good for all applications, but generally used when the ECM has a high horsepower tune and additional fueling is not desired.

ATLAS 40 – Improved throttle response and economy with a 40 HP gain. Useful for mild to heavy towing or when excessive exhaust gas temps (EGTs) are a concern. Good for trucks without head studs.

ATLAS 80 – Improved throttle response and economy with an 80 HP gain. Best for daily driving or very light towing.

HERCULES – Maximum performance with a 100+ HP gain. Not recommended for towing as it can increase EGTs. It’s recommended you run an EGT probe to monitor temps. NOT RECOMMENDED FOR TRUCKS WITHOUT HEAD STUDS.

All PHP purchases include a free FICM performance test to ensure output voltage is correct under load and all injectors are firing. We will contact you if we identify any issues.
