Might be worth a try.

Leaking up-pipes won't show using a boost-leak detector hooked up to the turbo, just fyi. Theoretically, you can hook the detector up to your exhaust pipe to check for a leak at the up-pipes, but I don't know anyone who has actually done it. I still reccomend building the detector, it is great for what it costs!

I am bringing this back from the dead. I just got back from a quick weekend trip with the missus. Drove from sea level to 10 and a half thousand feet, back to 5 thousand, then back up over the pass at 10.5 grand then back to sea level.

357 miles miles total. I averaged 14.5 on the flat part. Filled up at 6 thousand feet before starting the pass. If anyone knows the Sonora pass, they know it goes up to 10.5 grand and then comes down. A short drive at 15-27% grade the whole way.

Anyways, I kept the speed down because there was still snow and water (yes in june) and I got 15.7 mpg!!!!!

I couldnt believe it. Ok. well it was up and over the pass, about 50 miles of flats and then back over the pass.

I guess keeping it under 65 is the secret to mpg.

Anyways, it was an F-350, dually 4x4 with a big old high top ARE aluminum commercial camper, with only about 200 lbs worth of car camping gear...

Nice!

Slowing down a bit (55-60mph) has a HUGE affect on mileage in my truck. Suck's cause it takes longer to get anywhere, but sure is nice to see some kickass mileage when you get there.

That mpg sounds real good. I wish I could get some good figs on mine but I can't get the new to wear off yet. Guess that's why Cody says there is a learning curve w/these things.
