Westers 87/91 tune

[structEng07]

I was wondering if anybody with the wester's 87/91 tune for their 6.0 ltr selected the Max economy (Max power vs. Max Economy on the wester's form)for their tune. If so, did you see any mileage improvements (2mpg+)?

Not the 6.0, but the 8.1...and yes, I checked "max economy" on my Westers order.

 

I saw my MPG numbers rise from 9 to just over 10 MPG city, and from 11-12 to 13-14 highway. Got best of 15 MPG highway about three weeks ago.

 

Give it a shot...
