I run Hondata all motor, admitedly, with extensive modding, but all in all, for the base Hondata at $245, you can't beat the deal.

Paul is right about the TB it goes down to a 63mm bore, but honestly, you could get your Tb tapered by a local machine shop for a fraction of the price...

Any way, Hondata is well worth it, but just keep in mind, you'll need to find someone locally that sells them in addition to tunning it as well, otherwise you're sol. You may wanna do your homework before looking into buying either, the more you know, the better decision you'll be able to make.

Good luck,
