At the beginning of January, I replaced my stock exhausts with the Borla (Ford Racing) exhausts. The sound on the Borla exhausts is awesome, but I've noticed a problem with the Miles Per Gallon. I have noticed that my MPG have dropped about .7 or .8 MPG. Has anyone else noticed this? Is there a tune I can get to adjust this?

Your air to fuel might be a little off, get a diablo or sct canned tune.

Yep, a tune with fix it. Could you be driving faster to hear it? I know I do!

I noticed an increase with my FRPP's. Did you reset the computer? I did that after the K&N and the FRPP and I have NEVER seen a decrease in mileage beyond what my right foot contributes to.

Claytone

Did you have to custom tune after those mods? Or did you just reset the ecu?

I think Steeda's version of the Diablo has a tune in it for their mufflers and if Im not mistaken, they are the same muffler as the FRPP, made by Borla, but with Steeda written on it.

I was under the impression a tune was not needed for axle backs.

You don't, but it sure makes for good conversation.

FREAKO

Thats what I thought but for some reason Steeda has a tune for that in their Diablo Predator.....

I also didn't think that a tune was necessary for Axle Backs. I do think it will help though. Now I just need to save up for that tune.
