Jb4 is the best piggyback (by your terms best tune that doesn't re program the BMW ECU)
Bootmod3 offers unparalleled features and flexibility so it is considered by most the best flash tune available
Both methods are safe proven by thousands of users.

(sorry not really sure how to do quotes yet on here)
So ultimately a piggy back just modulates signals into the existing CPU where as these "stand alones" actually re program the code on the original CPU itself permanently?
Is there anything additional that a stand alone modifies well that a piggy back cannot interact with?
Thanks!!!
