Are you guys getting video or just audio? When I click on the link, it downloads to my laptop, then fires up Quicktime (by default) and shows the bar moving as if it's playing but there's no sound and no visual. Then a dialog box pops up and says some important quicktime updates are needed. It provides a link to these supposed updates. Instead, it presents about 10 aftermarket codex sources with none of them indicating 'use me to play your video. I'm the one that's missing...'. I just picked one randomly, downloaded and installed it. No change on the video though. I then fired up windows media player and directed the URL to the link. Now it 'plays' audio but there's still no video.
Nah... This thread can go to rest. I'll start something new when everything actually works. 
Here's a video of one of the runs I made. They were all cut short at 4800 rpm.

PS. Yup. that was a misfire early in the run. That has been fixed...

Just to wet your appetites... Have you guys seen this?

Look how soft he leaves and still turns this phenomenal time/mph. This was his first pass ever with this setup. He didn't get it spooled up on the line but when boost hits. O...M...G.... This pass was 18psi on drag radials. Full street trim.

the dyno isn't creating enough load to build boost... On the street, I could hit 14psi by 3000 rpm. On the dyno, it didn't hit 14psi until ~4300. Timing started at 30* at 2psi at 2300rpm and dropped steadily to 24* at 14psi (we were playing it safe for pump gas).
I was shooting for a perfect street tune moreso than pure dyno numbers.

BTW, when are you going to try and get it fixed?

sounds like my car on the dyno, full boost (14psi) at 4200rpm, but on the street it makes that way sooner....different problem than yours, buti blew out spark and my graph looks way different.
Similar problems at similar rpm, but look at the difference in graphs. Interesting to compare

Their wideband was close to the end of the pipe and was picking up stray oxygen. Mine was reading 11.7-11.9 through the entire run.
I kept my foot on the floor for 5 seconds after it hit the mysterious rev limiter to log more info one time... RPM stayed steady at 4800. Timing stayed at 24*. It went rich and boost just dropped off. It does it even on the street, right at 4800rpm.
As I posted earlier, I'm somewhat convinced it has something to do with the dwell time of the coils (inductive delay) where the timing is falling off based on too long of a delay... Anyone have experience with this?

hmm... the demo tune and manuals for the FAST classic box all have 96 uS as the inductive delay. The FAST XFI manual says:
"You should not have to change this parameter with most popular engine applications. Always start at 40 uS.
This parameter is used to compensate for the varying delays that occur with different types of crank sensors. These varying delays often cause ignition-timing error that will increase as engine RPM increases.
For inductive pickup ignition systems, leave this parameter set to 40 uS (microseconds). For other types of ignition systems, this value can be altered to reduce or eliminate ignition-timing error as a function of RPM. This error will show up as either unwanted timing advance as RPM increases or unwanted timing retard as RPM increases.
Increasing the value in this parameter will reduce unwanted timing retard.
Decreasing the value in this parameter will reduce unwanted timing advance."
So, if that 40uS is right, I should be advancing timing too much, which is definitely not what is happening. I wish I had a timing reference pointer so I could play with that setting until I had it perfect across the RPM range... I might be fabbing something up soon...
