Had the Injected tune in my '13 SE 5 speed hatch, and now have an Injected tune in my '14 DCT Ti. Extremely pleased in both cases.
As I've stated in other threads, the tune smooths out the power band particularly in the 1st to 2nd shift, allowing for smoother, fault free starts.
I've been to Injected's location on several occasions, and it is very impressive from several standpoints---large, clean, modern. Aric and his team know what they're doing, and they really deliver good customer service.
