Update
Just finished installing Holley Commander 950. I am very impressed with the EFI. Motor hadn't been started since dec and with a fairly close base map and it didn't roll over more than 4-5 seconds and fired up and idled. Wow. Now the fun part of tuning fuel map. With the breather on, it hides itself well.

I like that!! I'm very curious about some of the new self tuning throttle body set ups,they all have the ability,reportedly,for one to fine tune without the need for a laptop.FAST even makes a 2-4 bbl set up.

That FAST dual quad EFI set up is supposed to be able to support some serious power too.

Thanks. I was a little overwhelmed by the tuning aspect , but with some instructions from a friend who is a guru with EFI, the old Holley system is fairly easy to tune. A lot more time consuming compared to the newer auto-tune systems on market, but was definetly much cheaper.
