here is the break down of all the kits availible

t1r turbo- bigger injectors, cat delete, doesnt pass smog, more tuning, need to wire it.

hks turbo- is carb legal, less tuning, wiring harness is plug in direct with no wiring, but hp numbers are less than the t1r and you need an authorized hks tuner to do any additional tuning.

kraftwerk base kit- keeps cat so it is smog legal but they have not got carb legal yet, hondata reflash for the ecu so no wiring problems. if you are running a full exhaust (header, cat delete, b-pipe, axleback) you will need the injector upgrade package. more power is made by changing the pulley to make more psi and get a new tune.

There are tuners not affiliated with HKS that can still tune the F-Con. So it doesn't need to be certified HKS tuners.
What do you mean by more tuning / less tuning?
