Guys:

I couldn't find a good thread (yes, I did a lengthy search) comparing the pros & cons for these 2 (Dinantronics Sport Performance Tuner vs JB+) simple tuners. I found comparisons for different BMW models, just not X1's. I just want a little bump for my wife's 2017 X-drive. We can only get 91 octane here in AZ but wanted real feedback on these. They are selling for the same price these days.

Thanks
