I've noticed my gas milage has dropped badly since it got cold. Cold start enrichment sucks.
EGR cooler leaking probably doesn't help either...

That is highway cruising.
I drive my car hard, ask anyone that knows me. Why do you think I break parts? To name a few, turbo, DS, traction arms, sheered off flywheels bolts, OEM crank pulley. Nope, I guess I don't drive it hard. :sarcasm:

Highway, at steady speed, best I've seen yet is 30mpg on this last stroker motor. (Tons of coated parts, free flowing exhaust etc.)
Stock it was mid to high 20's IIRC. (I've had the car since 95 or 96, I can't remember exactly when I bought it anymore, might have been the summer of 96.)
Downpipe with no cats was a big bump in fuel economy and power.
If yours is doing poorly, check your O2 sensor as noted, and that you have not melted, or clogged up the stock cats. (There are two, one just under the turbo, and one under the floor of the car.) Most aftermarket Down Pipe designs remove both cats.
Good luck.

I get about 400km/tank of gas. Stock gas tank, average driving, good mix of highway/city driving. I got it up to 475km/tank once driving like an old lady.

LOL, my custom downpipe removed both.. A 3 inch pipe is a 3 inch pipe..
If I had it all to do over again, I'd just go with a new exhaust manifold from China, adapter to raise and rotate the turbo, the MPT-70, at least 680cc injectors, and start out right v/s building it up 4x.. LOL
Not sure our cars really need a 4 inch exhaust, but it's possible if you dont' mind the thing scraping around from time to time..
In any case, the better you let the engine draw in air, add fuel, burn it and then expell it, the more power your going to make, and the less pumping losses you have.. So you get better fuel economy from a higher performance engine..
That is till you put your foot in the throttle... LOL
