Hey Guys, Have a 502 Ramjet in my 80 series Landcruiser. Seems as though it needs a tune, have read that from factory these motors have a "Boat tune" as they are most commonly used in boats it likes to run on the rich side and seems to only rev just past 3000 RPM while in gear but will rev to 5500 in neutral.

How are people tuning the 502 Ramjet, with the MEFI system? or going aftermarket EFI Systems?

Cheers.
