Ahh ok gotya. Yeh, earlier models are a bit cheaper. That sounds right.
Alternatives are ECUTEK which is upwards of $1600 for initial tune (MMS, Race Torque).
Tokyo Motorsport does open source tuning but seems to vary depending on how many hours they spend on the car. My initial tune with them was $1300. They also do ECUTEK.

Then there's Evolution-R who do open source tuning for cut-throat pricing of around $650 I'm lead to believe. Before opting to go there I suggesting doing thorough research using the search function on here as well as Google before committing to cheap tuning...
