Just wanted to post a compliment about HPP racing in Lewisville. I went and finally got my car tuned properly by Manny and it runs great. I have been to 2 other mustang shops in the area and the customer service was not very good to say the least. The tune i had kept putting the car into limp mode because there was way too much timing and it was setting off the knock sensor. Lone star performance could not figure out what was going wrong and didn't really seem to care either. The tuner there gave me some crap about making too much torque and the torque modules were shutting the car down. He didnt know what he was doing and didnt really care to help. Sorry for the rant but i hate poor customer service. Just letting anyone else who lives around north dallas know about them.
