So I've been thinking a lot about the possible benefits concerning EFI. Right now my car is doing great with the K-jet, no issues except for minor power fade out and stutter in high gears on the freeway. But my question concerning EFI in the Cost to benefit ratio. If its really that good, I just may consider doing an EFI job if the price is right. What am I looking at on average cost for an EFI conversion, and how difficult is it to do?
