I haven't use either the Holley or FItech but it seems like the way to go if you are planning future mods. The folks over on LS1tech seem to like the Holley efi better than the FItech efi.
Me I like the OEM GM efi. My builds are fairly mild so tuning the GM ECM is typically easy.
My biggest concern with any aftermarket supplier is will they be in business tomorrow? I'm not suggesting either company is going out of business but customer support after the sale is very important both in to regards technical assistance and replacement parts.
You are going to find replacement GM parts at the closest parts store.
