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.

Yes, I realize this. But taking into consideration that many of the aftermarket kits use OEM sensors and injectors, the aftermarket components that they provide consist of the electronics, harness, and enclosure(s). As to the electronics, if the aftermarket was trying to duplicate a system that the OEM's brought out last year, I would agree that it would be simpler and less reliable. But OEM systems have been used for, what, 35 years? In that amount of time if the aftermarket can't produce a reliable alternative to carburetion, it is by their choice.
