Mike - pulled this from one of mgoncalves posts on the other thread - sounds easy to get to:
"The address is 5720 s. Bueno Drive, Fort Collins, CO 80525. The shop is called PFI, they are an import performance shop but they seem pretty respectful of us diesel guys. To get there from I-25, my directions are to take the Harmony road exit (don't know the #) West to College (hwy 287). Then go South on College, until you see Tynan's car dealer ( they have a massive US flag, can't miss it). You'll turn East at the North edge of the dealers lot on Smokey Drive. Then a turn North on Bueno. I'll put up some signs once you're off of College. "
