Cobra, I thought I mentioned earlier that the ECU was controlling the engine to make it have 1200 HP or 35 MPG... maybe that wasn't clear.
Obviously you're not going to run 1200 HP on the street and still get 35mpg... but you (generalized, not YOU specifically) fail to equate that the 1200 HP is also at full throttle, and the highest power building point in the engine's rev range, which wouldn't be touched (normally) on the street.
For instance, if the engine built 1200 HP at 3200 RPM (not at all uncommon for a truck diesel, to have a power range so low, and extremely long gears), chances are, on the street, he's minus the funny gas, slightly detuned, and never actually hitting his max power range (probably driving around at not much more than half throttle, shifting under 2800).
It IS quite possible, especially on a ECU-tuned setup, to have both high HP and high MPG figures. Since most anyone that tunes ECU's can set them up to have multi-map features, which can be changed at the flip of a switch.
His car is OBD-2 diesel, so the banks six-shooter (name?) or the BullyDog diesel tuner could more than well do it for him, as a piggy back system.
