Another "Is Fuel Injection a Worthwhile Upgrade?" Question

Kern Dog said

You do realize that EFI was integrated in new cars primarily for emissions and economy, right?
The big car companies have a LOT more money to support the development of their systems and they are required by Federal law to warranty the emission systems for 5 years. NO aftermarket EFI company is under that obligation so their kits are far simpler and less reliable.

Interesting comment that FI is only about emissions and fuel economy. Totally ignores the fact that since MPFI has been broadly used in new car production there has been a marked uptick in motor performance, across the board. Everything from 295 hp v6 grocery getters to over 700 hp Hellcat motors have MPFI.
The reliability comment is also just as far off base. My MegaSquirt System uses the exact same sensors and injectors that a major OEM uses and that are under the 5 year warranty requirements. The fuel pump is from a major OEM supplier. Most likely that if I took the time to cross reference the part number it is also used in OEM production.
