My car was having some serious issues idling and restarting after the engine was hot. A local tuner worked on it part time for about 3 months but couldn't iron out the issues. After becoming very frustrated, and then posting on here for suggestions, I decided to haul the car 8 hours to Kurgan Motorsports. Of course, I poured through threads on the internet and found very positive reviews and unfortunately some serious haters as well. I can tell you that the minute I got there he was nothing but professional. The car was worked on for 3 months by a local tuner and would not idle without feathering the accelerator. The minute you take your foot off, the thing would die. Then you would have to wait a few minutes before it would start up again. I took Kevin with me, the builder to answer all the technical questions. Bob looked at the engine for about 5 minutes in the parking lot and asked some questions of the specifications. He pulled the SCT chip and put his base tune on it. Put it back in and it idled for about 10 seconds and then quit. He didn't say a word, pulled the chip, put another program on it, and put it back in. Boom, the thing idled. He got out of the car and said...how does it idle now?? Unbelievable. 15 minutes in the parking lot and he fixed it. He literally said..so are we done, or do you want me to tune it? Of course I wanted him to tune it. We stayed out of his way and watched him work. We spoke when spoken to and answered his questions. In 3 hours, the car put down 507 hp and is running amazing. I can see why people might get rubbed the wrong way with him...because everyone else is an expert. This guy has so much experience it's crazy. I would take any mustang I owned to him again and again to tune. I didn't see one thing to write bad about him. Worth every mile of the trip.
