You can't just slap in a Hondata and start tuning. Check out the site www.hondata.com. You can see that you'd need to spend over $1k to be able to do your own tuning. They also have a listing of their dealers/tuners so you might be able to find one pretty close to you. I have to drive over an hour to get to mine and he charges me $60/hour for tuning... plus, I have to pay $85/hour for the dyno. h:

If you want to make reliable power, be prepared to spend some money.
