Mine is 21+ psi custom tuned
I think both hondata and k tuner are similar except that some after market add ons like PRL cobra intake are more compatible with k tuner as they offer some options in the tune.
The one I’m using is the basic hondata ecu flash. I can make changes to the tune but the only downside is that everytime i have to make changes in tune i have to visit the tuner as only he has access to it which i think is same for the basic k-tuner too unless you opt for K2 where you can have control on your tune and also access to real time stats like AFR, boost and knocking which is also available in hondata Flashpro.
It all comes to your own preference but what i have noticed is that almost everyone is using K-tuner on their civic turbos.
