Nowadays that’s a fairly common body mod. You can physically remove it, but it’s impossible to tune it out of the pcm.Or, I might some day catch a STD so before I do I'll just chop off my.... NO!!!!!!!!

It’s nothing new.Nowadays that’s a fairly common body mod.
I remember Emo Philips giving her a hard time. Decrying her for the danger she posed. ''Throwing that thing out of the window onto the street - someone could have slipped and fell on it.''Just call Dr. Morana Bobbitt,she'll fix you right up!!!
I don't think mine could possibly be any dumber than it is. I achieved this level of dumb in my '96 4.3l by first removing the TBI, and tossing it straight into the trash, along with it's distributor cohort. Next, I removed the intake. Rather than tossing the intake, I kept it, and used it for a boat anchor. The intake was replaced by an aluminum Edelbrock, and the TBI with a 500cfm 4 bbl Edelbrock Performer. The distributor was replaced by a 16,000V HEI. Timing that was all kinds of fun and interesting!! EGR was deleted, MAF didn't prove necessary, the PCM was unplugged and joined it's friends in the trash can. Next came the removal of about 9 miles of wires, and the alternator was replaced by a one wire GM. Instrument cluster was removed from dash and replaced with a modified digital LED from Intellitronix, and another mile or two of wire removal followed from behind the dash. I also replaced the steering wheel with an NRG quick release, so there wasn't a whole lot of need for air bags, or the connecting wires and sensors. Speed sensor and digital dash didn't com well, so I swapped it with a gps speedometer. Entire exhaust was replaced with 3" true dual from the headers all the way back, and all of the O2 sensors went with it, but I did put one back in and ran it to the AFM gauge that was added to the A support, along with vacuum and fuel pressure guages. High pressure fuel pump was removed and replaced with the primary pump from an '88 Ford Ranger. All of these upgrades along with a few others allowed me to travel across the desert at a brisk 160mph with literally a ton or better of cargo weight. Only downside that I really noticed is that you have to pay much closer attention to ALL of your gauges and have an understanding of how the systems interact together. No more "dummy" lights to rely on.Heys guys, this may be a newb question as I don’t know a whole lot about tuning. But has anyone ever tuned a vortec engine to run on as little sensors/electronics as possible? I know egr and rear o2 can be tuned out, anything else? I may have heard somewhere that you can tune the pcm to use MAP for air/fuel ratio, and other sensors can be deleted, not sure is that’s true.
I am guessing something like this would require a 411 swap. And we can disregard emissions legality for now, this is purely hypothetical. I just want to know if its possible to dumb down a vortec to be as simple as a TBI, or even simpler.
Because if the PCM sees no vacuum it thinks the engine is under a full load and will start dumping in fuel and advance timing.If MAF is more accurate than MAP for fuel/air anyway, then is MAP technically necessary? Also would there be any cons to tuning out the cam and crank sensors, since those weren’t listed as an absolutely necessary sensor to make the car run?
I understand these are dumb questions but I’m trying to learn more about tuning and efi systems
If you want simplicity then yeah carburetor is the way to go lolI don't think mine could possibly be any dumber than it is.
