Overall, it's worth it for the power bump. The mid range torque boost is definitely noticeable in all gears. It pulls really well up to about 5500rpm and then kind of feels like it flattens out, but I think that's to be expected since that's how it felt stock. Driveability is fine as well. I've been using the default +3.0 psi setting and maybe when the weather cools, I'll try race mode since I use 93 octane.

I checked for any hidden codes with ISTA-D and there were none so it doesn't seem like this box will trigger any of those. My only wish is for an iOS version Of the app to be ready and the overall app needs to be made a little more intuitive. It does get the job done though and it's in beta, so technically it's still a work in progress.
