EFI help

Don't think too much about the 'self tuning' stuff all those EFI kits mention.
Yes they can get the mixture tuned to be around stoich or some user-entered value, but how do you know that's what your engine wants?
The actual tuning still comes from the knowledge and experience of the owner.

A day on a chassis dyno is about the only quick way to get a proper timing and fueltune in your engine.
