There's J Tran, there is also Europower in south Houston. They do good work from what I hear. I really like Powerfab Autosports in north Houston as well, I take my car there for everything, they do excellent work. You can take it to Eurocharged, they work on German cars but always want to work on my car. And another option is HP motorsports out in Katy. When my cousin dropped off his z06 there, the owner told me he loves working on ISFs and that he thinks they're fun cars. Lots of places in Houston!
