SCT tuned Expedition

[cj41foley]

Well I've had my SCT on my Expy for a week now. The in dash fuel mileage guage was reading 14.6 most all the time, now it reads anywhere from 15.5 to 17. I think the fuel mileage has definately went up at least a mile or two per gallon. I've noticed a lot better throttle response with it also. Don't get me wrong it's not fast by any means, but thats why I have my 6.0. I've got it set on the 87 octane setting and when I burn the rest of this tank out I'll probably turn it up to 89 and see what it does.

please keep us posted, what does it add like 15 hp?

[cj41foley]

Supposed to be 22 hp, I'm sure thats on 93 octane setting though. And I'm just trying to save gas with it.

Took the SCT out of the Expy last night. My wife stopped and filled up and we figured the mileage and it was the same. Man I drove around for bout 2 weeks without it in my truck, put it back in last night and when I left my house this morning I was really happy I about had forgot how fast my truck was.

so it didn't do much?

how about power gain?

[cj41foley]

I only tried it on the 87 setting and there was a 87, 89, and 93 setting. Even on the 87 setting you could tell a great bit more throttle response but it wasn't fast by any means.

so whats the mpg gain?


my buddy at work just installed a K&N cold air intake and he said his mpg went from 14 to 17 on highway drivin
