I reccomend Sid. He will set it to exactly the numbers you want, and only occasionally screw up. (Hey, just being honest, every mechanic has an off day, but he will make it right when he does screw up.)
Make sure you mention you are with the Subaru Autocross group... If you mention Debbie's name, you get a good discount, and if you mention me, you pay extra.
There is also a discount for cash once he gets to know you, or if you are nice and ask...
