i was wondering how accurate the message center on the mustang is after installing a predator tune. I am mostly interested in the 87 octane tune. Is it way off, or pretty accurate. I read in the diablosport website, and they do say the car computer can vary in MPG calculations, but they dont state the accuracy. Thanks

 

I have the predator 87 tune and mine seems to be pretty accurate still. I have been keeping an eye on my gas gauge and the message center and seems to be right on.

 

Same here, I'm running the 91 Octane tune and the message center is within a tenth of a gallon when I manually calculate it.

 

93 octane custom tune is dead on accurate.

 

cool, thats what i was hoping to hear.

did you see much of a MPG improvement after using the predator?
