Maptunerx- tune to run 89 octane


#1

Is there a map tuner X tune to run 89 octane valve tech marine fuel ? 2016 SVHO cruiser
Tired of schlepping the fuel containers to the dock


#2

I’d add octane booster before re-tuning for 89.


#3

What kind would you recommend?
Any kind of search I did brought up mixed results - Manny saying that octane booster is snake oil and none of it works just a waste of money - Thus wanting to tune the motor to 89 -

Do they have E85 at the docks?

This is the type of stuff that actually works. People use it in high performance cars all the time, and it has a proven track record. Look it up and verify for yourself.
