Help with AEMTuner and EMS4

Is there anyone on here that knows how to use AEMTuner that I can get to look at my map/harness?
I went to get my Spyder tuned at J.E.M at the end of last month but Adam was unable to even get anywhere on it as it refuses to rev over 3500rpm, it's like it hits a rev limiter and just splutters and coughs the moment it hits that rpm. Also the car runs fine on the stock ecu, just too rich so it has to be either the harness, ems4 or a incorrect setting on the ems4 map.
