Need a 3.8 Turbo expert in Houston

I'm in Houston and my turbo is acting odd - hiccups and all. I'd like an expert/specialist to look at it and diagnose the problem. Any help would be appreciated!

This is my first post. Glad to be a member!
I`m no expert or specialist . . but I do read a lot of books . . LOL . . Good to talk to you, I hope I was able to steer you in the right direction, hopefully other members will respond to your questions, it will help if you be more specific also. Check the Texas Region for next gathering of the TR`s
