EFI question

I run the FAST on mine, I have about 1000 mi on it so far. FAST does "self tune" fuel, by adjusting the VE table to match the desired AFR that YOU CHOOSE for that point on the graph, so Dyno tuning or datalog tuning is still 100% necessary. It also does not tune spark, and cannot use the factory knock sensor. So spark tuning is up to the operator as well. I like the system, and have my car pretty dialed in at this point and am very happy. However the learning curve is steep initially. My Hemi kit came with NO base tune when purchased but I think they come with a generic program for the Hemi now.
