Wow!
Some people gotta learn the hard way. Plus as the old saying goes, there's more than one way to skin a cat. Some need to let it go. Arguing with strangers on the internet is like punching your face to spite your foot.
A. You won't get any gain from an aftermarket coil over a stock one. But if you like red or yellow colored parts on your engine, buy what suits you.
B. MSD boxes are and still are, designed to promote low speed response. Back in the day, high overlap cams and large carburetors would dump fuel into cylinders that would not effectively ignite, causing engines to load up and have poor throttle response. The MSD box would provide multiple spark pulses that would ignite those poor fuel air mixtures at low to mid range rpms. After say 2500 rpm ( or where ever the box was set), the multiple pulses would go away as the air fuel mixtures would stabilize and engine vacuum would catch up to the cam. Plus your engine rpm would be quicker than the pulses could be fired.
I know of a couple of guys back in the day, when these trucks were "new", that ran MSD boxes off roading. They supposedly improved throttle response at low speeds which were perfect for rock crawling. Because of the design of the EFI system, and the limitations of the MSD, you probably won't see any huge gains on a stock truck.
C. I can't comment on different brands of throttle bodies. Unlike a carburetor or TBI, a throttle body on a 2nd gen is a pretty "dumb" device. It's a sensor mounting platform with two metering plates. Only the MAP sensor is vacuum driven, everything else is dependent on the throttle shaft position.
I run a throttle body that many people don't care for. But I can assure you it functions as it should. I also run an air cleaner that a lot of people don't buy into either. But throttle response is pretty instantaneous compared to my previous setup, and my truck accelerates harder up to shift point with the new TB. Does that mean it makes beau coup horsepower? No. But it's sure doing something.
D.I wouldn't do any engine mods without having a programmer to work with. Max gains won't be realized.
Experience is a great teacher, but it can be expensive and painful. Some people just like pain though and want to walk through the same path of broken and abandoned parts. So be it!
And I'm out!
