Questions for those who switched to EFI...

There are a few members here that are running that system, and a guy i work with... I havent heard a bad thing yet, starts, drivability, and power... I have read a ton of reviews and articles and everyone sounds great. I was gonna do it but went hemi swap instead. I will be using fasts hemi kit, also with the self tuning option. Dont have it going yet, but i am sure it will be worth the work/money...
