So just got my heart broken on dyno

I wouldn't exactly call the XEDE useless. It can adjust timing in tenths of a degree, whereas the stock ECU can only adjust timing in 1 degree increments. I also love how we have already come to the conclusion that it's the piggyback unit, when there could be so many other issues or reasons for the numbers.

..... The Xede has plenty of advantages.. A flash is one thing.. You sure you are running the correct map? You sure you cam gears are at its correct setting? How do you know its the Xede? Get a custom tune cause it sounds like you don't have one.. And don't be so quick to jump the gun.. Any boost leaks?

In sig ----> SSAC Turbo Manifold(best bang for the buck)
NOT best bang for the buck, hate to say it. Also I would check and make sure its not cracked, because that will seriously rob you of power. Feel around it when the car is running, if you feel air your in trouble.
I would also suggest a retune if thats not it.

To the average Evo guy with customized engine work the Xede is a paperweight; It's too hard to get it tuned or serviced by the 3 guys in the country that tune them REGULARLY.

I've got to think there was something going on to make those numbers. Seems a little premature to blame the exede.
What was your boost level, AFR's, ignition timing?

Sure the Xede has it's advantages, but in reality, Verrrrrrrrrrry few people know how to tune them and the off the shelf maps don't always apply to certain applications.

Anyway, that doesn't resolve the present issue (assuming there is one). Where that is concerned, the tuning is the first thing I would consider.

I'm not saying the Xede isn't a good product. It's a Betamax in a world of VHS and support is hard to come by if you don't want to experiment by tuning it yourself.
We know you can tune it, but most others don't want to take the risk.
So yeah, I agree with you about the tune, but another tuning vehicle like an ECU flash, AEM, etc.. for tuning might be in order for him because he's in Texas, about 1500 -2000 miles from the 3 experts. And guys are setting track records with SAFC's and lots of shops can tune those... .
Bottom line is he should probably use a tuning method that is convenient.

Let's not get sidetracked here.
If tuning IS an issue here (and we don't know that it is), what one would do is retune with ECU Flash (Xede fuel and ignition settings at '0'), and then use the Xede's better resolution to tweak those settings. As for what's required to do this, anyone who's seen the Xede user interface knows it just doesn't get easier or more user-friendly.
The first thing this individual should do is find a Dynojet and someone who can retune his car. That will be more revealing than 100 posts worth of speculation.
