For me it ended up being much cheaper to get an AEM programmable engine management system than get a conversion harness, an ECU, socket the ECU, and then add on the Hondata system. BUT, I was looking at a stage 4 system with an EPROM programmer. If you are just looking to have someone else tune your system and get it going, Hondata is IMHO right for you.

However, especially with a turbo car I would strongly think about the stage 3 instead of the stage two. For a couple hundred bucks more you get that stutterbox, and that will enable you to have your turbo spooled right off the line.
