Thats the old way of doingecu tuning with daughterboard added to ecu & the map chips can be swapped out for different pre written tune stages.
Not as good as road or rolling-road custom mapping & modern nistune board or standalone ecu.
that said they can be good & if chip maps tweaked a bit more for your car.
Would never use them without monitoring fueling & knock though .

I would never use a pre written tune without being able to monitor how the engine is performing. In saying that if the tune is based on similar mods to your car, you will potentially save money, as the tune may only need small refining to suit your car

Look on the sxoc and the 350z club. They love h dev and a lot of people on there said his plug n play chips are good
