Looks like a RaceChip with less aggressive mappings. Probably be better off just getting the RaceChip GTS Black which is proven.

Nothing against race chip as we offer both tuners, but how did you get to this conclusion?

Both Dinan and Racechip use the same hardware, and both are proven. If anything, Dinan has been in the tuning game for much longer than Race Chip.

Neither brand released its mapping; how did you conclude it's less aggressive than Race Chip?

I think we both agree it's the same hardware for RaceChip (seems to be the supplier) and Dinan ... and let's throw Carbahn in there for good measure. The only aspect piggy backs (any of them) have control over is the boost. The amount and rate at which it is added based on changing the signal intercepted to the DME. More boost means more power all else being equal. We can't change the timing, only the octane rating to combat detonation. I'm "guessing" since none of them publish their maps, each company has their own special maps loaded on the same hardware.

So if you then compare dyno charts and/or published power increases from both websites ...

Dinan:
"More Power: Max gains of up to +98 HP and +103 lb-ft TRQ (Crank); +86 HP and +94 lb-ft TRQ (Wheel)."

RaceChip GTS Black:

"+121 HP (+89 kW)+164 TQ"

So far I like it. I didnt wanted anything to wild on it. Im going to turn it more into a show SUV than a racing one.

If you are looking for performance a reflash its better but I think there isnt one available.
