what is the stock model for a 97 honda prelude jmd ecu and should i go with a honddata 1 2 or 3 will it change anything if the only mods I have is dc header, air intake, future plans are to get bigger injectors and turbo?what would be the best thing right now to get instant power

 

any help here would be nice

 

you cannot use hondata with OBD2; for instant power, go NOS.
