Programmable ECU's (Was GM TPI tips for a newbie)

[Charles Brooks]

I've looked at several of them but frankly I'm not sure what
I should be looking for in a programmable EFI system. The
Accell DFI system seems popular and so do the Haltech
products. I must have looked at a dozen Mfr.'s. I was leaning
toward the Holley system but after receiving several messages
on the problems and deficiencies they have I changed my mind.
Which system(s) is/are considered the best?
