EFI -3G hemi

For me the advantage is having the performance 90mm mechanical throttle body for better response , and I plan on adding a performance camshaft , maybe on down the line and the system will self tune , no need to rely on a cmr or custom flash once you buy this setup. JMO
I believe if you are planning on running the factory 5 spd auto then you would be better off with the factory ecu.
