I recommend JMS, and you can get one from them in between $300.00 and $350.00.
You'll be glad you did this mod later on if you decide to start interchanging h/c/i.
I had a custom dyno tuned Autologic chip done and I also just passed an emissions test today. The chip wasn't even programmed for emissions but rather for performance, but it still passed.
It was $650 for the chip including 2 hours of dyno tuning time.
