setting up safc

Ok so I was playing around with my safc and I noticed that my gauge rpm and the apexi safc rpm is about 1k rpm off. If anyone knows exactly how to set this thing up that would be sweet. I notice some extra boost lag I'm guessing its from the apexi safc thinking its lover rpm than it realy is. I know you have to set the sensor on karmen and the cylender on 6 with the arowe pointing up but what does all the other setting have to be at? /ubbthreads/images/graemlins/banghead.gif

I`m pretty sure it`s 2 and the arrow pointing top right.

You set the cylinders two either 2 or 4, depending upon which wire you tapped to get the rpm.

thanks guys I was looking on some websites and it said that it should be on 6 cly with the arrow pointing up twards the right. How do I know what wire is 2 or 4? lol Im sorry Im very noob still /ubbthreads/images/graemlins/confused.gif I basicaly bought this car the way it is now with the exeption of 3" exhaust and a k&n air filter
