MEFI Tuning

We keep changing and have lots more information comming your way!

We specialize in marine power plant tuning based on the popular MEFI1, MEFI2, MEFI3, MEFI4, MEFI4A, and MEFI4b (Marine Electronic Fuel Injection) ECU platforms used widely by MerCruiser. Our services are available both for the serious competitor and the weekend warrior.

If you have a desire to add more punch to your MEFI controlled power plant give us a call. We would love to hear about your needs and experience.

We take your tuning needs seriously. We do not take the cookie cutter approach to tuning. All of our tunes address specific combinations of components that have been dyno tested then fine tweaked on the water under actual conditions.

If you have a special need and are looking for package combinations we will go the extra mile to make sure you are happy with your investment. It is as much our reputation as it is your satisfaction.

For you owners that have the VOLVO driver package we have a package to convert your MPI/VOLVO systems to the DELPHI MEFI 4B controller. This includes ECU and all the necessary wiring harnesses.
