WOW what an improvement already. freeway MPG is up from around 54mpg on my normal commute, to closer to 59mpg! ....wish i had done that mod a long time ago..... rear underbody diffuser is next....

Where are the pictures of the bumper modification!!!!! I probably had 4-5 inches blocked with my bumper skirt and lawn edging combo. But I removed the lawn edging when I lowered the car 2 inches. Really haven’t noticed any negative effect without having the lawn edging. I would like to block 1-2 more inches, but the edging is much larger than that and I am kinda enjoying not scrapping everywhere.
Wish I had your warm weather. My mpg has been falling to the 54-55 mark lately.
Good luck with the MMO. I have found it to be useful as well. Can’t really comment on the speed aspect of it as I have a VX transmission, but it allows lean burn at lower RPM’s which seem to the one of the limiting factor on lean burn (not speed.)
