I have the Holley Commander 950 system on a street/strip 440 in my Barracuda. The drivability is great. I can start it on a cool morning and it just idles. I take my son to daycare and go to work with it about three days a week. I also race it about five times a years at the local dragstrip. I have $2500 in the complete system, that includes every hose clamp. I would encourage anyone who drives their car to try EFI.
