Bolt on EFI kits....opinions?

[tsutomu27]

hey guys,

just curious what peoples' opinions are on the EFI kits? the ultimate preference (for me anyway) would be a full on LS swap. but i can't make it work financially nor logistically right now (the blazer is about to be my daily).

although i want any and all opinions, i'd be really happy to hear from someone who's actually used one.

what kind of improvements did you see? (just ease of starting? throttle response? mpg?)

thanks guys!

**also, the ones i've "looked up" are: MSD , FAST EZ-EFI 2.0, Edelbrock E-Street, and Holley
