Can you use the S200 w/o boost option on a turbo'd car? or is there a way a tunner can add boost option to it?

 

no, you need the s200b with the boost option.

 

You will be better off just upgrading to the s300 rather than adding the boost option to the s200. With the s300 you also get the ability to use boost control, it's fully user tunable, has many extra features a s200 does not have and is a million time easier to use.

 

Well the tune will be done by a certifed hondata tuner, So user friendly isnt an issue for me. Although price is, Im looking to spend 300 or less and that outs me out of the s300 reach
