Self tuning EFI

Recommended Posts

Anyone have experience with the self tuning EFI? 


I'm looking at a Holley Sniper for my 454.  I plan on running the external fuel pump.

Currently running an 800cfm double pumper that is tired and sitting on a single plane manifold.  Start up takes 5 to 10 min to warm the damn truck up with no choke.  And by the time I get it running, the exhaust fumes just about tip me over.  Keep in mind that this is a street cruiser, so I want the ease and reliability of EFI.  I'm over the carb.  


Some locals tell me that the self tuning is garbage, but I've seen numerous success videos online. Any input is appreciated.
