i does seem to be a little bit better as far as power i think it does build some power it still has to shift on small grades to keep the speed up with the 4 place enclosed trailer but not as bad as before it still revs to 3-4000 rpm to build it's power but it is building it. still no codes and still geting the 6-7 mpg unloaded

That 6-7, is that stop-and-go around town type stuff, or all on the highway?
And how are you figuring that?
Oh, and fill in your location in your User Profile so we can tell what type of gallons you are talking about

around town stop and go as of this past week figuring by miles traveled (and yes i have checked by mile markers to check mileage for accuracy) by gallons to refill so last fill was 30 miles on odometer and 5 gallons to refill to full (full by gauge reading and fuel coming out of filler neck)

You need to do a longer run than 30 miles! You may need to make a special trip. Get out on the hwy and drive streight though at least 100 miles (50 out and 50 back). with only thirty miles there are to many varibales with idle time and such to get a good accurate reading. Also I realize your fillng up to the filler neck (I do the same) but this is often times a cause for less mielage as many vehicles will leak out excess out the vent. I don't know if the SD will do this or not. Also I have found you need to fill at the same pump facing the same direction as some pumps will have the concrete leaning one way or another and this will affect how much you can get in there for throwing off you calcs, especially on only 30 miles!

A few years ago there was more than a few guys in here with similar complaints. Sometimes it was a fuel filter. Sometimes the ECM had to be re-flashed. Or the MAF was clogged or dirty. But I don't remember a time when the problem wasn't found and rectified. I think his Y-pipe is constricted or smashed. That's how it feels, or a bad catastophic converter maybe ?

There was little girl with a little curl....
Remember that nursery rhyme?
...and when she was good she was very, very good, But when she was bad she was horrid.
Kind of reminds me of today's computer-controlled engines.
When they run good, they run very, very good
And when they run bad, they run horrid.....
