Need performance engine mechanic in West Michigan

[pitschfork]

I have a 2006 Roush with an MMR turbo charged engine in it (built by MMR). Recently replaced turbo and car is idling rough. Not pleased with current mechanic's ability to correct this issue. Looking for mechanic familiar with high performance engines that can diagnose and correct without a "high performance price." Suggestions and contact information welcome.

Try Steve Morris Engines in Muskegon. He is located at 750 E. Ellis Rd, Muskegon, MI 49441 They are very familiar with tubro charged engines and have a dyno onsite.
