So I've been tuning with my Portfueler now for a while and it's just very basic to me now and I'm ready to take the step into getting MS. My question is, my buddy has MS2 on his car and is very familiar with it, if I got a MS3 from Symtech, would he have any difficulties helping me with it? Also, the tune from Symtech is our stock tune correct? Stock fuel and stock timing tables? I'm leaning to MS3 just because the price isn't all that much more for it.
