39 cars. 2 powerstrokes. 1 cummins. 1 tdi. Every single diesel I've done at a minimum an intake/exhaust to, and on all trucks I saw an improvement in mileage. With intake/exhaust my superduty was sitting at 21mpg city, my cummins around 20mpg city, my HD 18mpg city, and my tdi... well, it's a tdi....

don't bring the TDI into this. that doesn't even compare. thoser what? a 1.3L or something? what's your elevation where you are?

Ya I know thats why I didn't elaborate into that one :lol: It's a 1.9 btw.

But I'm about sea-level... 600ft over, if that.

1.9... dam! that's a big one there...

That could play a part tho. if i go up to about 12,000 feet. it's a smokey pig that only gets 13 mpg. at 5- 6,000 feet i get about 16 mpg.

Really?! I had no idea that elevation played that big a part in mpg/smoke!!!:s:

600 feet vs 6,000 feet. you'll get 20. i'll get 16

Dang diddly I didn't know the impact was that great
