it is very very important that every wire has a good connection otherwise you may have problems. make sure also the a/f wires are going the right direction, the first time i installed it i had it backwards and had the same problem. The directions say something to the effect of yellow in white out, which i interpreted as yellow in to the ecu, white out away from it, but that is wrong, Yellow is the input and leads away from the ECU and the White is the output and runs into the ecu, try that you may have luck

Last time I talked to sound performance, they were cautious about being about to tune with the SAFC without switching to a return fuel system and running FI... they weren't exactly confident about running it NA
They have to take the oportunity that for now they hold the "secret" to tune "without" major problems the fuel management of our cars. For me 1,100 is a bit to much, I would put those to better use by saving a little more money and buying an AEM EMS.
I had an app. with them like 4 months ago to get it tuned and dyned for like $150, but I cant remenber the exact price. They where saying how I would be the first that they would try it on and they where not for sure if it would work............So, i did the smart thing and stepped back to see if it will work on someone else's car FIRST..............
.....and plus I know another shop that has done the trick and it works and they will do it for me for less...........you will see more from this shop very sooooon...... 
Heres from there site: "Something of interest for the Scion tC guys, we are currently researching and developing a turbo kit for you. This kit will allow you to trounce a supercharged tC, as well as the new Civic Si. We will keep you updated on new items we come up with as we continue to try things out on our project tC."
