Slant Six EFI....

I've never understood going to the trouble of switching to efi, only to use tbi.
Kind of agree, there are benefits to TBI over carbs,...but getting a precise and correct fuel map is critical. Lotsa luck. Lets take how many TBI's ran like suck right from Mopar, late 80's-early 90's Rams/Ramchargers-felt flat at times & gawdawful mileage, certain 2.2/2.5's where they missed the target & revised the intake to add coolant heating/cooling. The trouble & cost not worth settling for TBI, & ANY system really needs intake manny temp realtime input for the Slanty.
