Clicked the link cause I had the same questions, no one in my area can tune (Fairbanks Alaska), but I'm not a dummy when it comes to advanced math and computers. I can tune a carb, but haven't played with EFI much. I have an SAFC2 tune (tweeked for my car myself, took tune from another car) and I hear once you start pushing the big boost/hp SAFC2 tunes are dangerous and un-reliable. Hopeing to get an AEM EMS, wondering same question that Tavenger5 is, some threads in this EMS forum are a bit mind scratching, but I think thats more of cause I have never seen the software.
Anywho, wouldn't have posted, but I noticed Tavenger5 had a 3.0 Avenger... I had a tc1 body kitted avenger
