EFI control

[John Dammeyer]

I have a question about this.  I've seen on Crank & Chrome the use of the
Holley Fuel Injection upgrade kit.  Is this also poor quality?  Can someone
with experience in these various EFI systems post a comparison with a good
and bad listing of each.  We;'ve seen Cable/harness/connectors as Bad for
SDS but what's good about it?

Thanks,

John Dammeyer
