The 1st Dinan unit produced lower than expected dyno results. Click on the dyno link in my sig. Intuitively, this did not make sense unless the modded throttle valve was not opening correctly. Other variables secondary to DME inputs from the multitude of sensors (e.g., radiator outlet temperature sensor, charge air temperature sensor, coolant temperature sensor, evaporator temperature sensor, fuel temperature sensor, exhaust backpressure sensor, intake pipe pressure sensor, engine collant temperature sensor, blah blah blah) may be at play. I refer you to the previous thread and links to Steve Dinan's white paper regarding Dynamometer Testing and the Modern BMW Engine.

This seems to be the logical next step.
