-The Pcm does backup airflow calculations by measuring the pressure drop across the TB.THis is the only way to accomplish backup in case of MAF fail due to the widely fluctuating VE's effected by VVT.
-System is Wideband feedback equipped
-Fuel injectors flow 122lbs/hr @ 2200psi (it's rumored that the LLT's are ~96lbs/hr)
-On demand pump has never lost pressure on me, even at 200hp more than stock.
-Pump control could potentially unleash 3000psi and a bit more breathing room on the stock injector.
-System is "torque demand" based. Meaning that your right foot is commanding 0-100% torque. The pcm then calculates the optimum throttle angle, cam angle, and in the LNF's case boost pressure to achieve the torque being requested.
- Is very protective of the engine and will go into halfpower mode when it doesnt like what it sees.
-Individual cyl knock detection.

its almost like gm knew what they were doing when they built this thing.
