Yes but I was told by the guys who wrote my programs for my 6.0l that to get that amount of power from the stock setup the ecu basically gets lied to, if you run the obd2 port gauges they will lie to you. Maybe my info was incorrect?
The guy's who sent you some programs they very much didn't write (they might have piddled with an editor someone else wrote with very limited knowledge of the actual program itself - they are kicked inside docs from the OEMs and there is NO reversal taking place among the domestic ECUs) have about as much clue about what's going on as the #2 distributor of the same brand handhelds, who also fucked up a simple tune on Corey's car by making a bunch of n00b ass mistakes.
To get "that amount" of power from the stock setup, your ECU is reprogrammed for different injector timing, injector duration, and fuel pressures. Short of one of the piggybacks, no, your ECU is not being lied to. As far as "OBD2 port gauges" there are a number of ways they could be wrong. If you are logging off of your handheld they default to a delayed feedback but can be changed to instantaneous. Second, if the gauge is a generic one meant to read a raw hex value from RAM which is then interpreted by the gauge, if you rescale said parameter inside the ECU's code then suddenly the gauge is wrong because it doesn't know what the ECU is doing.
