EFI help

with so any different brands of EFI out on the marker what are the better brands. i was looking at the QF, or holley brands.. but is there others that are better. im looking for something that will me really good performance.

Holley Sniper is a great product with good bang-for-the-buck. Lots of other benefits that people don't know about such as you CAN manually tune the Sniper if you had to. Most other "self-learning" systems can't do that. Example is a radical cam that doesn't produce consistent vacuum at idle of if you have open headers. Tune the idle manually and pick the RPM for learning to kick in.
