1. Fuel pressure with static fuel pressure regulation must be set to [43 psi + maximum boost] or 54 psi (whichever is greater).
2. Fuel pressure with manifold referenced fuel pressure regulation must be set to 54psi during idle. (boost signal after throttle body)
3. Fuel pressure with boost referenced fuel pressure regulation should be set to 58 psi with vacuum off. (boost signal before throttle body)
4. Use L2 fuel system to operate outside these parameters.

Ordered the cold air and tuner combo. Best tune I have had. Really woke up my 5.0
