In case anybody didn't see me blabbering it all over the internet, today I loaded my Livernois/MyCal Stage 4+ tune today! Initial test drive was exhilarating! (even being used to SCT Stage 4) With in the first mile, I scared a 300 Hemi driver just by looking at him.
EDIT-After the excitement of having a new toy wore off, and some further testing, I wish I would have just stuck with the SCT Stage 4.
