One more TDI...with a twist

Hi there,

I just got interested in ecomodding and it has nothing to do with my TDI.

With the kid now, saying the wife's hatchback Aveo was small is an euphemism. So we just bought a 2008 Hyundai Elantra to replace her car.

Being used to my ecomodless TDI which gets 50 mpg on the highway just by setting the cruise at 70 mph, I had to do something about the Elantra's economy which EPA rating is 33 mpg on the highway.

So here's what I plan to do:

Front grill block
Smooth out the under-car
Lower the suspension
LRR tires
Potentially add removable rear wheel well covers (I really don't like the look but I will probably want them for long highway trips)
I'd really like to experiment with VGs too.
Some sensor tweaks affecting fueling, for now I can think of IAT and MAF electrical mods (I have quite a lot of experience with sensor mods on the TDI).
Maybe a fuel economy oriented turbo setup eventually

Well, that's pretty much it. You guys look like a fun bunch to hang out with.

Have a nice day,
