It seems anecdotally that some people experience tangible performance boost with the RC, some don't -- and so, too, with the BMS piggyback. I'd prefer not to have to shell out $2500 for the Dinan, of which there is sparse feedback on the various forum postings. The car is fast enough stock, but hey, why are we all here if we didn't want to amp it up a bit more.

I really don't understand how these tune chips are that inconsistent. Did something change in the assembly parts that we were unaware of? Did us guys with older chips get the working versions? I got mine back in 2014 when I wrote up the thread for it. To this day, it's been nothing but a champ. I've owned both chips... Both changed the 50i for the better, but I preferred the RC Ultimate over the BMS stage 1 because it just was better in terms of performance and reduction of throttle lag.
