One of my customers who I sold a Mustang to last year came in today to get have his tires toped off with noitrogen. Got to talking with him and asked him if he did anything to it..........Turns out that he was a little busy, having installed a turbo set up on it. Man that thing was tight. Asked him who tuned it, and he said that our very own Tom did a street tune on the car. Said that he has no issues and that he did an awesome job on it. Says thanks to tom, he thinks he should be at 450 to the tire.....any info on this Tom?
