I have had good luck with Salem Brothers on Warner just West of Hardy. They maintained my 90MTX and have done well by me on all my other fleet. Eddie C. is their Ford Master Mech and he is very helpful and knows the SHO as good as any I have found. In fact I wouldn't have bought my 95MTX if I hadn't known that I had Eddie as a resource. They are spendy at a shop rate of $80/hr, but they have the dyno and all the latest. Mark Salem also has a list of other recommended shops on his web site.
We have some real sharp guys as part of the club, but I hate to take regular advantage of them when they have their own list of stuff to do. Also it's hard to get together sometimes when you need something done.
Hope this helps
