What's the pros/cons of the JB+ vs Dinantronics Sport Performance Tuner? I plan to only run 91 OCT gas and am interested in mostly low-end gains and passing power on the hwy.

I am new to forum and to G05. I had a E60 545i many moons ago. It's been so long I have to re-sign up here LOL

And while we are on the subject, why would someone go JB4 vs JB+ or go Dinantronics X vs the Sport Performance Tuner? Oh, and I noticed some of you prefer RaceChip, they also have the S version that's comparable to the SPT and the JB+ it seems, how does one pick??

I am in GTA Canada if anyone wants to point me to a shop that's reputable and has amazing service for newbies like me.
