so im running a hondata s100 setup in my boosted eg.i wanted to change a couple things in my tuning. is there a way i can do it myself? what would i need? or it it only done by a tuning shop? im very knowledgeable in the tuning aspect of life so im confident i can do it my self i have tuned other cars myself.

 

You would need the romeditor v4 software license & an eprom chip burner.
Your best bet is going to be to go to a hondata tuner or upgrade to hondata s300.
