The other possible scenario is that you have a major (MAJOR!) exhaust leak at the exhaust manifold, either between the manifold/head or the manifold/turbo.
Just to get my cracks in.... I don't know how so many people can't get a stock ECU/MAFS/injectors/turbo car running properly!
^^ What he said. Ignitor is either working or not working, and has exactly zero to do with how a car is boosting. You either have timing WAY off (and thus arent making any power, even off boost... OR you have a huge leak so the turbo isn't spooling.
The other option is that you went "OMFG HUGE TURBO" and bought one off a semi or something, and has entirely the wrong compressor map for how your engine flows. You said it was a stock SR setup, so I don't think this is the case, but ... I have to suggest it.
