Hey Norcaler I figured you would know,

Is there any difference in MPG between ATT and non-att tunes, using your timing tune?

I thought ATT might be lower due to a tighter housing when cruising at little load on the highway.

Usually you will get better mpg in town with att and less on the highway, and no att will give you less in town but better on highway.

Tomey,

I don't prefer the ATT tune since I tow up some pretty big grades, so the data I have from my customers is all I can share. Their data has proven to me that the ATT tunes produce less mpg's when compared to the non ATT.

I hope that helps.

Interesting...

Looks like I'm building a non-att file tonight!!!! I know with my w/ATT file, boost is RIGHT NOW... so it will be interesting to compare back to back.

thanks for the feed back.
