Bad gas milage!

[BayBoss]

I have a predator tune with c&l intake and borla exhaust. my gs milage has gotten worse and worse and now it is down to under 20 on the freeway with regular driving. Any siggestions would be great.

Reflash?

Hi, I dont know about the preditor tune, I have the brenspeed 93 octane tune on my 07 GT. But you might reflash your ECM again and see if you have what you had when it was good. Or returning to stock, and then flashing your performance tune again.

Just an idea. Hope you get it fixed soon..

No idea. I have about the same mods (predator tune, intake, headers, off-road h) and my gas mileage has only gotten better on the highway at about 24mpg.

i don't get it. why do people buy "PERFORMANCE CARS" modify them, the bitch about fuel mileage? if you're that worried about your mpg's then maybe you should have purchased a hybrid or moped.

DITTO!!!!!
Except for the Flows, my car is stock(performance wise)and with the auto I've never seen more than 22 MPG. I have not bitched once about it either. I even intend to swap out the stock gears for a set of 4.10s in the next month or so. I still won't care what the MPG does, it will be a blast to drive!!!!!
