im having a rilly loud bacfiers since i installed a new jordan mufller and a hight performence air filter.
i have got the ecmspy program with the maps but i still cant get the engine runnig as it should.
what should i do about it?

I would just buy a tuned ECM from erikbuellracing.com
I'm guessing you mean you got a Jardine exhaust not a Jordan. If so then buy a pre programmed ECM with the Jardine mapping on it.
