Ok, went out and beat on the truck and logged some dead stop to full throttle in 4wd. Torq2 and warhammer,
Torq box set at 0%- Fuel rail pressure was 26,000-27,000psi
set at 50%- FRP-25-26,000psi
set at 100%-FRP-22-23,000psi
Boost was the same- 38ish psi
Pulls harder down low and mid range with box turned up.
Top end seems about the same.
Smoke clears up good at any setting.
So this kinda backs up what everyone says about the 6.7 having less fuel.
Anyone know what pid to read boost on the dd. Can only find manifold gauge pressure in volts??
