Top 10 reasons I ditched the fuel injection on my LS1/LQ9:
1. drive by wire/ electric gas pedal and related programming
2. anti theft programming
3. fuel pump
4. CEL/SES trips
5. needs tune each time a mod is made
6. car was already (stock) set up for carb (tank, lines, throttle cable etc)
7. giant wiring harness
8. EFI does not necessarily make more power
9. Holley carb new for less than $300
10. Been there done that with Megasquirt
Did I mention it needs tune each time a mod is made?
