yup,
i built an MS and harness per scott's instructions (though some conflicting info in his diagrams were found) back in January, but had not yet been able to find time to get it going. Yesterday I hired the services of paul to help with the installation, find/repair some trouble spots, and tuning.
BOOOYAAAH! the sonofabitch started! We got some tuning time in (some tuning time is still needed). i can certainly say that the MS really has a higher engine controlling quality over the stock ecu. it transitions perfectly from vacuum to boost and idles tremendously better. two thumbs up!
Now i just need to learn me some megatune.....

Well, the premade by DIY DB37 cable does not have the same pinouts as his diagram (to be fair to scott....it is possible that it was a diy mistake.....i just don't know). basically the injector circuits in the harness were backwards (thick green & thick blue)....so we just flipped the pins on the yellow connector side to correct it.

32/33 - green - INJ1
34/35 - blue - INJ2
36 - brown - spark out
