The way I see it, it is like the OP want a flash tune just because it is a flash tune.
point #1. Piggy seems to be making a lot more power than flash at the moment, GIAC stage 2 sounds promising but still not ready for order yet. Smoothness is one thing people rave about with their flash tune, but JB3 2.0 seems smooth enough. I'm dying to try GIAC Stage 2... just to see the differences..
#2. Flashing the BMW ECU is requires a long time, hence, a battery or charger solution is necessary, which not everyone would want to spend the extra $.
#3. Can the tune manufacturer actually make $$ off of a take home flash? or can they make more by making a piggy back?
#4. more of a question than a point.. Do we even know what a flash can do on a BMW ECU that a piggy can't? Maybe this engine is better off tuned with a piggy than a flash?
