... a good Rotary tuner shop in the Colorado/Wyoming/New Mexico area? Preferably in Denver, CO?

Well, for those of you who are interested, here is a reply I got when I posted this same question to the general forum:
In south Denver, there's The Mazda Honda Shop. Luis and Tony Rivera have been tuning and racing rotaries for many years and are very experienced.
Mazda-Honda Shop
(303) 771-1500, 6328 E County Line Rd, Littleton, CO 80126

Tony Rivera also runs a pure racing oriented shop,
