Okay I just bought a 93 Mazda RX7 that recently had a rebuild on it. It now doesn't hit boost and tops off at 4300 RPM's getting crappy fuel mileage. It has the mods that are listed below. I'm looking for a good dyno and tune near Rapid City, SD. If anyone knows of anyone please let me know. I don't even care if I have to drag it as far as Denver to get it done. Any help is appreciated. Please PM me with any known shops, names, numbers, etc so I can get this done ASAP. Thanks

 

you ever resolve these problems? I have a freind up by the ND border (bowman) that could help you out hes very knowledgeable in rx7s.
