call jerry@eurocharged.com or adam@eurocharged.com and discuss with them what they can do for you. My NA roadster started out with ,I think, 179 RWHP. Did a few low cost mods and the tune, now 211.4 RWHP and I have no complaint with TR. They have other locations too, not just Houston. Ask them about that too. Get names, phone numbers, e-mail addresses at the location you want to use. Phone # in Houston is: 281-206-0076. My first tune added about 24 RWHP, they will re-tune free if you make another mod. I think it is a great deal.
